/FN0024/ AccessSFR

long int AccessSFR(LONG wAddr, void *IpData, LONG iFlags);

This function writes or reads data into the special function registers of the MSP430 device. (implemented in PRGS320.dll versions 1.05 and higher).

wAddr: SFR address that should be accessed. Allowed values: 0x0000−0x1FE (see the memory map of the corresponding device)

IpData: Pointer to the data to be written, or buffer which should receive the read data

Flags: The bits in Flags control the operation of AccessSFR()

iFlags:

SFR_READ (0x00)

SFR_Write (0x01)

Example: IFuncReturn = AccessSFR(long:0x0020, &IpData, 0)
