Chapter 1 MC9S12Q Device Overview (MC9S12Q128-Family)

the Flash EEPROM memory in the memory map (ROMCTL). At the rising edge of RESET, the state of

this pin is latched to the ROMON bit.

â¢ PP6 = 1 in emulation modes equates to ROMON = 0 (ROM space externally mapped)

â¢ PP6 = 0 in expanded modes equates to ROMON = 0 (ROM space externally mapped)

1.3.4.19 PP[5:0] / KWP[5:0] / PW[3:0] â Port P I/O Pins [5:0]

PP[5:0] are general purpose input or output pins, shared with the keypad interrupt function. When

conï¬gured as inputs, they can generate interrupts causing the MCU to exit stop or wait mode.

PP[3:0] are also shared with the PWM output signals, PW[3:0].Pins PP[2:0] are only available in the 80-

pin package version. Pins PP[4:3] are not available in the 48-pin package version.

1.3.4.20 PJ[7:6] / KWJ[7:6] â Port J I/O Pins [7:6]

PJ[7:6] are general purpose input or output pins, shared with the keypad interrupt function. When

conï¬gured as inputs, they can generate interrupts causing the MCU to exit stop or wait mode. These pins

are not available in the 48-pin package version nor in the 52-pin package version.

1.3.4.21 PM5 / SCK â Port M I/O Pin 5

PM5 is a general purpose input or output pin and also the serial clock pin SCK for the serial peripheral

interface (SPI).

1.3.4.22 PM4 / MOSI â Port M I/O Pin 4

PM4 is a general purpose input or output pin and also the master output (during master mode) or slave

input (during slave mode) pin for the serial peripheral interface (SPI).

1.3.4.23 PM3 / SS â Port M I/O Pin 3

PM3 is a general purpose input or output pin and also the slave select pin SS for the serial peripheral

interface (SPI).

1.3.4.24 PM2 / MISO â Port M I/O Pin 2

PM2 is a general purpose input or output pin and also the master input (during master mode) or slave

output (during slave mode) pin for the serial peripheral interface (SPI).

1.3.4.25 PM1 / TXCAN â Port M I/O Pin 1

PM1 is a general purpose input or output pin and the transmit pin, TXCAN, of the CAN module if

available.

1.3.4.26 PM0 / RXCAN â Port M I/O Pin 0

PM0 is a general purpose input or output pin and the receive pin, RXCAN, of the CAN module if available.
