2.3.37 PS0 / RXD0 — Port S I/O Pin 0
PS0 is a general purpose input or output. When the Serial Communications Interface 0 (SCI0) receiver is
enabled the PS0 pin is configured as the receive pin RXD0 of SCI0. While in reset and immediately out
of reset the PS0 pin is configured as a high impedance input pin. Consult the Port Integration Module
(PIM) PIM_9E128 Block Guide and the SCI Block Guide for information about pin configurations.
2.3.38 PT[7:4] / IOC1[7:4]— Port T I/O Pins [7:4]
PT[7:4] are general purpose input or output pins. When the Timer system 1 (TIM1) is enabled they can
also be configured as the TIM1 input capture or output compare pins IOC1[7-4]. While in reset and
immediately out of reset the PT[7:4] pins are configured as a high impedance input pins. Consult the Port
Integration Module (PIM) PIM_9E128 Block Guide and the TIM_16B4C Block Guide for information
about pin configurations.
2.3.39 PT[3:0] / IOC0[7:4]— Port T I/O Pins [3:0]
PT[3:0] are general purpose input or output pins. When the Timer system 0 (TIM0) is enabled they can
also be configured as the TIM0 input capture or output compare pins IOC0[7-4]. While in reset and
immediately out of reset the PT[3:0] pins are configured as a high impedance input pins. Consult the Port
Integration Module (PIM) PIM_9E128 Block Guide and the TIM_16B4C Block Guide for information
about pin configurations.
2.3.40 PU[7:6] — Port U I/O Pins [7:6]
PU[7:6] are general purpose input or output pins. While in reset and immediately out of reset the PU[7:6]
pins are configured as a high impedance input pins. Consult the Port Integration Module (PIM)
PIM_9E128 for information about pin configurations. PU[7:6] are not available in the 80 pin package
version.
2.3.41 PU[5:4] / PW1[5:4] — Port U I/O Pins [5:4]
PU[5:4] are general purpose input or output pins. When the Pulse Width Modulator (PWM) is enabled the
PU[5:4] output pins, individually or as a pair, can be configured as PW1[5:4] outputs. While in reset and
immediately out of reset the PU[5:4] pins are configured as a high impedance input pins. Consult the Port
Integration Module (PIM) PIM_9E128 Block Guide and the PWM_8B6C Block Guide for information
about pin configurations. PU[5:4] are not available in the 80 pin package version.
2.3.42 PU[3:0] / IOC2[7:4]/PW1[3:0] — Port U I/O Pins [3:0]
PU[3:0] are general purpose input or output pins. When the Timer system 2 (TIM2) is enabled they can
also be configured as the TIM2 input capture or output compare pins IOC2[7-4]. When the Pulse Width
Modulator (PWM) is enabled the PU[3:0] output pins, individually or as a pair, can be configured as
PW1[3:0] outputs. The MODRR register in the Port Integration Module determines if the TIM2 or PWM
function is selected. While in reset and immediately out of reset the PU[3:0] pins are configured as a high
