|

;//
|

;// For these examples, code_start is the first code that is executed after
|
||||
;// exiting the boot ROM code.
|
||||
;//
|
||||
;// The codestart section in the linker cmd file is used to physically place
|
||||
;// this code at the correct memory location. This section should be placed
|
||||
;// at the location the BOOT ROM will re-direct the code to. For example,
|
||||
;// for boot to FLASH this code will be located at 0x3f7ff6.
|
||||
;//
|
||||
;// In addition, the example DSP2833x projects are setup such that the codegen
|
||||
;// entry point is also set to the code_start label. This is done by linker
|
||||
;// option -e in the project build options. When the debugger loads the code,
|
||||
;// it will automatically set the PC to the "entry point" address indicated by
|
||||
;// the -e linker option. In this case the debugger is simply assigning the PC,
|
||||
;// it is not the same as a full reset of the device.
|
||||
;//
|
||||
;// The compiler may warn that the entry point for the project is other then
|
||||
;// _c_init00. _c_init00 is the C environment setup and is run before
|
||||
;// main() is entered. The code_start code will re-direct the execution
|
||||
;// to _c_init00 and thus there is no worry and this warning can be ignored.

;// Function Prototypes:

;//
|
||||
;// Uint16 DSP28x_DisableInt();
|
||||
;// and void DSP28x_RestoreInt(Uint16 Stat0);
|
||||
;//
|
||||
;// Usage:
|
||||
;//
|
||||
;// DSP28x_DisableInt() sets both the INTM and DBGM
|
||||
;// bits to disable maskable interrupts. Before doing
|
||||
;// this, the current value of ST1 is stored on the stack
|
||||
;// so that the values can be restored later. The value
|
||||
;// of ST1 before the masks are set is returned to the
|
||||
;// user in AL. This is then used to restore their state
|
||||
;// via the DSP28x_RestoreInt(Uint16 ST1) function.
|
||||
;//
|
||||
;// Example
|
||||
;//
|
||||
;// Uint16 StatusReg1
|
||||
;// StatusReg1 = DSP28x_DisableInt();
|
||||
;//
|
||||
;// ... May also want to disable INTM here
|
||||
;//
|
||||
;// ... code here
|
||||
;//
|
||||
;// DSP28x_RestoreInt(StatusReg1);
|

|

;// TITLE: Simple delay function
|
||||
;//
|
||||
;// DESCRIPTION:
|
||||
;//
|
||||
;// This is a simple delay function that can be used to insert a specified
|
||||
;// delay into code.
|
||||
;//
|
||||
;// This function is only accurate if executed from internal zero-waitstate
|
||||
;// SARAM. If it is executed from waitstate memory then the delay will be
|
||||
;// longer then specified.
|
||||
;//
|
||||
;// To use this function:
|
||||
;//
|
||||
;// 1 - update the CPU clock speed in the DSP2833x_Examples.h
|
||||
;// file. For example:
|
||||
;// #define CPU_RATE 6.667L // for a 150MHz CPU clock speed
|
||||
;// or #define CPU_RATE 10.000L // for a 100MHz CPU clock speed
|
||||
;//
|
||||
;// 2 - Call this function by using the DELAY_US(A) macro
|
||||
;// that is defined in the DSP2833x_Examples.h file. This macro
|
||||
;// will convert the number of microseconds specified
|
||||
;// into a loop count for use with this function.
|
||||
;// This count will be based on the CPU frequency you specify.
|
||||
;//
|
||||
;// 3 - For the most accurate delay
|
||||
;// - Execute this function in 0 waitstate RAM.
|
||||
;// - Disable interrupts before calling the function
|
||||
;// If you do not disable interrupts, then think of
|
||||
;// this as an "at least" delay function as the actual
|
||||
;// delay may be longer.
|
||||
;//
|
||||
;// The C assembly call from the DELAY_US(time) macro will
|
||||
;// look as follows:
|
||||
;//
|
||||
;// extern void Delay(long LoopCount);
|
||||
;//
|
||||
;// MOV AL,#LowLoopCount
|
||||
;// MOV AH,#HighLoopCount
|
||||
;// LCR _Delay
|
||||
;//
|
||||
;// Or as follows (if count is less then 16-bits):
|
||||
;//
|
||||
;// MOV ACC,#LoopCount
|
||||
;// LCR _Delay
|
||||

Interface Function prototypes

For each 28x Flash API library, the function names are of the form:

Flash<DeviceNum>_<Operation>()

|
||||
Where <DeviceNum> is the device: ie 2808, 2806, 2801
|

<Operation> is the operation such as Erase, Program...
|

|
||||
For portability for users who may move between the F2808, F2806 and
|
||||
F2801, the following macro definitions are supplied.
|
||||
|
||||
Using these macro definitions, the user can use instead make a generic
|
||||
call: Flash_<Operation> and the macro will map the call to the proper
|
||||
device function
|
||||
|
||||
Note except for the toggle test function, all of the function prototypes
|

are compatible with F281x devices as well.

Notes:
|

Memory blocks on F28335 are uniform (ie same

physical memory) in both PAGE 0 and PAGE 1.
|
||||
That is the same memory region should not be
|
||||
defined for both PAGE 0 and PAGE 1.
|
||||
Doing so will result in corruption of program
|
||||
and/or data.
|
||||
|
||||
L0/L1/L2 and L3 memory blocks are mirrored - that is
|
||||
they can be accessed in high memory or low memory.
|
||||
For simplicity only one instance is used in this
|
||||
linker file.
|
||||
|
||||
Contiguous SARAM memory blocks can be combined
|
||||
if required to create a larger memory block.

Notes:
|

Memory blocks on F28335 are uniform (ie same
|
||||
physical memory) in both PAGE 0 and PAGE 1.
|
||||
That is the same memory region should not be
|
||||
defined for both PAGE 0 and PAGE 1.
|
||||
Doing so will result in corruption of program
|
||||
and/or data.
|
||||
|
||||
L0/L1/L2 and L3 memory blocks are mirrored - that is
|
||||
they can be accessed in high memory or low memory.
|
||||
For simplicity only one instance is used in this
|
||||
linker file.
|
||||
|
||||
Contiguous SARAM memory blocks can be combined
|
||||
if required to create a larger memory block.

The 'targetConfigs' folder contains target-configuration (.ccxml) files, automatically generated based
|
||||
on the device and connection settings specified in your project on the Properties > General page.
|
||||
|
||||
Please note that in automatic target-configuration management, changes to the project's device and/or
|
||||
connection settings will either modify an existing or generate a new target-configuration file. Thus,
|
||||
if you manually edit these auto-generated files, you may need to re-apply your changes. Alternatively,
|
||||
you may create your own target-configuration file for this project and manage it manually. You can
|
||||
always switch back to automatic target-configuration management by checking the "Manage the project's
|
||||
target-configuration automatically" checkbox on the project's Properties > General page.
