Chapter 1 MC9S12HZ256 Device Overview
1.5.6.28 PS5 / MOSI â Port S I/O Pin 5
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 / MISO â Port S I/O Pin 4
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 / TXD0 â 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).
1.5.6.31 PS0 / RXD0 â 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).
1.5.6.32 PT[7:4] / IOC[7:4] â Port T I/O Pins [7:4]
PT7âPT4 are general-purpose input or output pins. They can be configured as input capture or output
compare pins IOC7âIOC4 of the timer (TIM).
1.5.6.33 PT[3:0] / IOC[3:0] / FP[27:24] â Port T I/O Pins [3:0]
PT3âPT0 are general-purpose input or output pins. They can be configured as input capture or output
compare pins IOC3âIOC0 of the timer (TIM). They can be configured as frontplane segment driver
outputs FP27âFP24 of the LCD module.
1.5.6.34 PU[7:4] / M1C1(SIN)P, M1C1(SIN)M, M1C0(COS)P, M1C0(COS)M â Port U
I/O Pins [7:4]
PU7âPU4 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 PU[3:0] / M0C1(SIN)P, M0C1(SIN)M, M0C0(COS)P, M0C0(COS)M â Port U
I/O Pins [3:0]
PU3âPU0 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.
