Table 2-12. Port S Pins PS7-0 (continued)
PS4
• The SPI0 MISO signal is mapped to this pin when used with the SPI function. Depending on the
configuration of the enabled SPI0 the I/O state is forced to be input or output.
• 20 TSSOP: The SCI0 RXD signal is mapped to this pin when used with the SCI function. If the SCI0
RXD signal is enabled and routed here the I/O state will be forced to input.
• 20 TSSOP: The PWM channel 2 signal is mapped to this pin when used with the PWM function. If the
PWM channel is enabled and routed here the I/O state is forced to output.
• 32 LQFP: The PWM channel 4 signal is mapped to this pin when used with the PWM function. The
enabled PWM channel forces the I/O state to be an output.
• 20 TSSOP: The ADC ETRIG2 signal is mapped to this pin if PWM channel 2 is routed here. The
enabled external trigger function has no effect on the I/O state. Refer to Section 2.6.4, “ADC External
Triggers ETRIG3-0”.
• Signal priority:
20 TSSOP: MISO0 > RXD0 > PWM2 > GPO
32 LQFP: MISO0 > PWM4 > GPO
Others: MISO0 > GPO
PS3
• Except 20 TSSOP and 32 LQFP: The SCI1 TXD signal is mapped to this pin when used with the SCI
function. If the SCI1 TXD signal is enabled the I/O state will depend on the SCI1 configuration.
• Signal priority:
48/64/100 LQFP: TXD1 > GPO
PS2
• Except 20 TSSOP and 32 LQFP: The SCI1 RXD signal is mapped to this pin when used with the SCI
function. If the SCI1 RXD signal is enabled the I/O state will be forced to be input.
• Signal priority:
20 TSSOP and 32 LQFP: GPO
Others: RXD1 > GPO
PS1
• Except 20 TSSOP: The SCI0 TXD signal is mapped to this pin when used with the SCI function. If the
SCI0 TXD signal is enabled the I/O state will depend on the SCI0 configuration.
• Signal priority:
Except 20 TSSOP: TXD0 > GPO
PS0
• Except 20 TSSOP: The SCI0 RXD signal is mapped to this pin when used with the SCI function. If the
SCI0 RXD signal is enabled the I/O state will be forced to be input.
• Signal priority:
20 TSSOP: GPO
Others: RXD0 > GPO
