Why does data sometimes missing during transmission using the RSPI?

Latest Updated:06/20/2013

Question:

Data is sometimes missing during transmission using the RSPI.

Answer:

When performing transmission in master mode during SPI operation, set the values of the RSPI sequence length specification bits (SPSCR.SPSLN[2:0]) and the number of frames specification bits (SPDCR.SPFC[1:0])
according to the combinations shown in the table "Settable Combinations of SPSLN[2:0] Bits and SPFC[1:0] Bits" for SPDCR in Register Descriptions in the Serial Peripheral Interface (RSPI) chapter of the user's manual: hardware.
