1.5.6.28
PS5 is a general-purpose input or output pin. It can be configured as the master output (during master
mode) or slave input (during slave mode) pin MOSI of the serial peripheral interface (SPI).
1.5.6.29
PS4 is a general-purpose input or output pin. It can be configured as master input (during master mode) or
slave output (during slave mode) pin MISO for the serial peripheral interface (SPI).
1.5.6.30
PS1 is a general-purpose input or output pin. It can be configured as transmit pin TXD0 of the serial
communication interface 0 (SCI0).
1.5.6.31
PS0 is a general-purpose input or output pin. It can be configured as receive pin RXD0 of the serial
communication interface 0 (SCI0).
1.5.6.32
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).
1.5.6.33
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.
1.5.6.34
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 or to measure the back EMF to calibrate the pointer reset position.
These pins interface to the coils of motor 1.
1.5.6.35
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 or to measure the back EMF to calibrate the pointer reset position.
These pins interface to the coils of motor 0.
