Signal Descriptions
SSI2_RXD
Receive serial data, multiplexed with GPT5_TIN; PC25
SSI2_FS
Frame Sync signal which is output in master and input in slave, multiplexed with GPT5_TOUT:
PC24
SSI3_CLK
Serial clock signal which is output in master or input in slave. This signal is multiplexed with
SLCDC2_CLK; through GPIO multiplexed with PC_WAIT_B; PC31.
SSI3_TXD
Transmit serial data signal which is multiplexed with SLCDC2_CS, through GPIO multiplexed
with PC_READY; PC30
SSI3_RXD
Receive serial data which is multiplexed with SLCDC2_RS; through GPIO multiplexed with
PC_VS1; PC29
SSI3_FS
Frame Sync signal which is output in master and input in slave. This signal is multiplexed with
SLCDC2_D0; through GPIO multiplexed with PC_VS1; PC28.
SSI4_CLK

General Purpose Timers (X6)
TIN
Timer Input Capture or Timer Input Clock—The signal on this input is applied to GPT 1–3
simultaneously. This signal is muxed with the Walk-up Guard Mode WKGD signal in the PLL,
Clock, and Reset Controller module, and is also multiplexed with GPT6_TOUT; PC15.
TOUT1
Timer Output signal from General Purpose Timer1 (GPT1). This signal is multiplexed with
SSI1_MCLK and SSI2_MCLK signal of SSI1 and SSI2. The pin name of this signal is simply
TOUT, and is also multiplexed with GPT6_TIN; PC14.
Note: TOUT2, TOUT3 are multiplexed with PWMO pad; GPT4 and GPT5 signals are multiplexed with SSI2 pads.
