Hello

I read the SSP0 in SPI mode , the datasheet says that after each byte(if my data size is 8 bits) is send ,the SSEL must return high,this is bad because we need to send several bytes in each transfer and after send all bytes we can return SSEL to high.(for example AD77xx ADCs from ADI need several bytes for communication and when we return SSEL to high it will reset the SPI interface in AD77xx).

How can I send several bytes without returning SSEL to high after each byte?


please check and respond this bug.
