Figure 24-80 shows a case in slave mode (full-duplex).
Only channel 0 can be configured as slave, but the chip-enable signal can be connected to any SPIEN[x] pin and then rerouted internally to channel 0 (the MCSPI_CHxCONF[22:21] SPIENSLV bit field [where x = 0]). For more information, see Section 24.4.4.4, Slave Mode.
Figure 24-81 shows the slave single mode, which can also be configured in transmit-only mode.
