Hi,

Is there any explanatory notes regarding how the SPI driver is supposed to work please? I'm having a hard time figuring out how Chip_SSP_Int_RWFrames8Bits(...) works when used in the SPI example code. It looks like it would run OK without the ISR but doesn't. Also why does the ISR contain a call to Chip_SSP_Int_RWFrames8Bits(...) ? The ISR seems to be run once per bit. I'm confused and wondered if there was any helpful notes somewhere.

TIA,

Rog.
