Function Documentation

Uint16 CsmUnlock ( )

Todo:: this function is implemented in DSP2833x_SysCtrl.c. However, there is a problem with the PLLSTS_BITS register.

Definition at line 267 of file DataStorage.c.

void InitDataStorageBuffer ( STORAGEMODE mode )

Initializes Buffer to hold data into internal memory

Parameters:

mode,:

Data storage can be configured to OVERWRITE, NOVERWRITE. In OVERWRITE mode, the writing mechanism is restarted once the buffer end is reached, In NOVERWRITE the writing is stopped at the end buffer.

Examples:: TIMotorLIBExample1/main.c, TIMotorLIBExample2/main.c, TIMotorLIBExample3/main.c, TIMotorLIBExampleHrdw/main.c, and TIMotorLIBExampleSw/main.c.

void InitFlash ( void )

Todo:: this function is implemented in DSP2833x_SysCtrl.c. However, there is a problem with the PLLSTS_BITS register.
