SYS_CLK1
SSI1 master clock. Multiplexed with TOUT.
SSI2_CLK
Serial clock signal which is output in master or input in slave.
SSI2_TXD
Transmit serial data signal
SSI2_RXD
Receive serial data
SSI2_FS
Frame Sync signal which is output in master and input in slave.
SYS_CLK2
SSI2 master clock. Multiplexed with TOUT.
SSI3_CLK
Serial clock signal which is output in master or input in slave. Multiplexed with SLCDC2_CLK
SSI3_TXD
Transmit serial data signal which is multiplexed with SLCDC2_CS
SSI3_RXD
Receive serial data which is multiplexed with SLCDC2_RS
SSI3_FS
Frame Sync signal which is output in master and input in slave. Multiplexed with SLCDC2_D0.
SAP_CLK
Serial clock signal which is output in master or input in slave.
SAP_TXD
Transmit serial data

1-Wire
OWIRE
1-Wire input and output signal. This signal is multiplexed with JTAG RTCK.
PWM
PWMO
PWM Output. This signal is multiplexed with PC_SPKOUT of PCMCIA, as well as TOUT2 and TOUT3
of the General Purpose Timer module.
General Purpose Input/Output
PF[16]
Dedicated GPIO. When unused, program this signal as an input with the on-chip pull-up resistor
enabled.
Keypad
KP_COL[7:0]
Keypad Column selection signals. KP_COL[7:6] are multiplexed with UART2_CTS and UART2_TXD
respectively. Alternatively, KP_COL6 is also available on the internal factory test signal TEST_WB2. The
Function Multiplexing Control Register in the System Control chapter must be used in conjunction with
programming the GPIO multiplexing (to select the alternate signal multiplexing) to choose which signal
KP_COL6 is available.
KP_ROW[7:0]
Keypad Row selection signals. KP_ROW[7:6] are multiplexed with UART2_RTS and UART2_RXD
signals respectively. Alternatively, KP_ROW7 and KP_ROW6 are available on the internal factory test
signals TEST_WB0 and TEST_WB1 respectively. The Function Multiplexing Control Register in the
System Control chapter must be used in conjunction with programming the GPIO multiplexing (to select
the alternate signal multiplexing) to choose which signals KP_ROW6 and KP_ROW7 are available.
Noisy Supply Pins
NVDD
Noisy Supply for the I/O pins. There are six (6) I/O voltages, NVDD1 through NVDD6.
NVSS
Noisy Ground for the I/O pins
