Figure 12-179 shows a case in peripheral mode (full-duplex).
Only channel 0 can be configured as peripheral, but the chip-enable signal can be connected to any SPIEN[i] pin and then rerouted internally to channel 0 (the MCSPI_CHCONF_0[22-21] SPIENSLV bit field). For more information, see Section 12.1.4.4.4, MCSPI Peripheral Mode.
Figure 12-180 shows the peripheral single mode, which can also be configured in transmit-only mode.
