wait
function
In the master mode (CKS3n2 to CKS3n0 bits of the CSIC3n register other than 111B), starting transfer
can be delayed by one clock, depending on the setting of the CSWEn bit of the CSIM3n register
(CSWEn bit = 1). The CSWEn bit is valid only in the master mode. In the slave mode (CKS3n2 to
CKS3n0 bits = 111B), setting the CSWEn bit to 1 is prohibited (even if set, transfer wait is not inserted).
When the transfer wait function is enabled (CSWEn bit = 1), the chip select outputs can be
During transfer wait (CSWE bit = 1) the chip select outputs (SCS3n0 to SCS3n3) can be configured for
an intermediate inactive level output of half a clock period by setting the CSMDn bit of the CSIM3n
register to 1.
