Device Overview MC9S12HY/HA-Family
1.7.3.26 PP[7:0] / PWM[7:0] / FP[7:0] â Port P I/O Pins [7:0]
PP[7:0] are a general-purpose input or output pins. They can be conï¬gured as frontplane segment driver
outputs FP[7:0]. They can be conï¬gured as pulse width modulator (PWM) channels 7-0 output.
1.7.3.27 PH[7:4] / FP[26:23] â Port H I/O Pins [7:4]
PH[7:4] are a general-purpose input or output pins. They can be conï¬gured as frontplane segment driver
outputs FP[26:23].
1.7.3.28 PH3 / SS / SDA / FP[22]â Port H I/O Pin 3
PH3 is a general-purpose input or output pin. It can be conï¬gured as frontplane segment driver output
FP[22]. It can be conï¬gured as the slave selection pin SS for the serial peripheral interface (SPI). It can be
conï¬gured as the serial data pin SDA as IIC module.
1.7.3.29 PH2 / ECLK / SCK / FP[21] â Port H I/O Pin 2
PH2 is a general-purpose input or output pin. It can be conï¬gured as frontplane segment driver output
FP[21]. It can be conï¬gured as the serial clock SCK of the serial peripheral interface (SPI). It can be
conï¬gured to drive the internal bus clock ECLK. ECLK can be used as a timing reference. The ECLK
output has a programmable prescaler.
1.7.3.30 PH1 / MOSI / FP[20] â Port H I/O Pin 1
PH1 is a general-purpose input or output pin. It can be conï¬gured as frontplane segment driver output
FP[20]. It can be conï¬gured as the master output (during master mode) or slave input pin (during slave
mode) MOSI of the serial peripheral interface (SPI).
1.7.3.31 PH0 / MISO / SCL / FP[19] â Port H I/O Pin 0
PH0 is a general-purpose input or output pin. It can be conï¬gured as frontplane segment driver output
FP[19]. It can be conï¬gured as the master input (during master mode) or slave output pin (during slave
mode) MISO for the serial peripheral interface (SPI).It can be conï¬gured as the serial clock pin SCL as
IIC module.
1.7.3.32 PT[7:4] / IOC0[7:4] / KWT[7:4] / FP[16:13] â Port T I/O Pins [7:4]
PT[7:4] are a general-purpose input or output pins. They can be conï¬gured as frontplane segment driver
outputs FP[16:13]. They can be conï¬gured as timer (TIM0) channels 7-4. They can be conï¬gured as key
wakeup inputs.
