RX23W Group 38. Serial Peripheral Interface (RSPIa)
38.2.11 RSPI Slave Select Negation Delay Register (SSLND)
SSLND sets a period (SSL negation delay) from the transmission of a final RSPCK edge to the negation of the SSLAi
signal during a serial transfer by the RSPI in master mode. Do not change the SSLND register while both the
SPCR.MSTR and SPCR.SPE bits are 1.
SLNDL[2:0] Bits (SSL Negation Delay Setting)
The SLNDL[2:0] bits set an SSL negation delay value when the RSPI is in master mode.
When using the RSPI in slave mode, set the SLNDL[2:0] bits to 000b.
