*1: tCSSU =SCSTR:CSSU7-0 × Serial chip select timing operating clock

*2: tCSHD=SCSTR:CSHD7-0 × Serial chip select timing operating clock

*3: tCSDS=SCSTR:CSDS15-0 × Serial chip select timing operating clock

Regardless of the deselect time setting, once after the serial chip select pin becomes inactive, it will take

at least five peripheral bus clock cycles to be active again.

Please see the hardware manual for details of above-mentioned *1,*2, and *3.
