Caution Be sure to set transmit data to the SlOp register before the clock from the master is started.
Remark 1. m: Unit number (m = 0), n: Channel number (n = 0, 1), p: CSI number (p = 00, 01), mn = 00, 01
Remark 2.
: Setting is fixed in the simplified SPI (CSI) slave transmission/reception mode,
: Setting disabled (set to the initial value)
×: Bit that cannot be used in this mode (set to the initial value when not used in any mode)
0/1: Set to 0 or 1 depending on the usage of the user.
