CCS: V8
I want to access an EEPROM(Microchip/25AA320A) via DSP SPI. I coded my program(attached in the end),
My program give me an waveform (below) for writting data to EEPROM. CS will be set to low before sending each data, and set to high after sending each data.
But, I hope "CS set to low before sending data, and set to high after sending ALL data. Just like my EEPROM required (see waveform 2)
The data include an 8-bit write command, an 16-bit address and an 8-bit data written to EEPROM
Any suggestion?

waveform2
Below is my program
