2.3.38 PS1 / TXD0 — Port S I/O Pin 1
PS1 is a general purpose input or output pin. It can be configured as transmit pin TXD0 of the Serial
Communication Interface 0 (SCI0).
2.3.39 PS0 / RXD0 — Port S I/O Pin 0
PS0 is a general purpose input or output pin. It can be configured as receive pin RXD0 of the Serial
Communication Interface 0 (SCI0).
2.3.40 PT[7:4] / IOC[7:4] — Port T I/O Pins [7:4]
PT7-PT4 are general purpose input or output pins. They can be configured as input capture or output
compare pins IOC7-IOC4 of the Timer (TIM).
2.3.41 PT[3:0] / IOC[3:0] / FP[27:24] — Port T I/O Pins [3:0]
PT3-PT0 are general purpose input or output pins. They can be configured as input capture or output
compare pins IOC3-IOC0 of the Timer (TIM). They can be configured as frontplane segment driver
outputs FP27-FP24 of the LCD module.
2.3.42 PU[7:4] / M1C1P, M1C1M, M1C0P, M1C0M — Port U I/O Pins [7:4]
PU7-PU4 are general purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive. These pins interface to the coils of motor 1. PWM output on
M1C0Mresultsinapositivecurrentflowthroughcoil0whenM1C0Pisdriventoalogichighstate.PWM
output on M1C1M results in a positive current flow through coil 1 when M1C1P is driven to a logic high
state.
2.3.43 PU[3:0] / M0C1P, M0C1M, M0C0P, M0C0M — Port U I/O Pins [3:0]
PU3-PU0 are general purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive. These pins interface to the coils of motor 0. PWM output on

output on M0C1M results in a positive current flow through coil 1 when M0C1P is driven to a logic high
state.
2.3.44 PV[7:4] / M3C1P, M3C1M, M3C0P, M3C0M — Port V I/O Pins [7:4]
PV7-PV4 are general purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive. These pins interface to the coils of motor 3. PWM output on
M3C0Mresultsinapositivecurrentflowthroughcoil0whenM3C0Pisdriventoalogichighstate.PWM
output on M3C1M results in a positive current flow through coil 1 when M3C1P is driven to a logic high
state.
