Device User Guide — 9S12C32DGV1/D V01.14
2.3.15 PE0 / XIRQ — Port E input Pin [0] / Non Maskable Interrupt Pin
The XIRQ input provides a means of requesting a non maskable interrupt after reset initialization. During
reset, the X bit in the condition code register (CCR) is set and any interrupt is masked until MCU software
enables it. Because the XIRQ input is level sensitive, it can be connected to a multiple-source wired-OR
network. This pin is always an input and can always be read. There is an active pull-up on this pin while
in reset and immediately out of reset. The pull-up can be turned off by clearing PUPEE in the PUCR
register.
2.3.16 PAD[7:0] / AN[7:0] — Port AD I/O Pins [7:0]
PAD7-PAD0 are general purpose I/O pins and also analog inputs for the analog to digital converter.
2.3.17 PP[7] / KWP[7] — Port P I/O Pin [7]
PP7 is a general purpose input or output pin, shared with the keypad interrupt function. When configured
as an input, it can generate interrupts causing the MCU to exit STOP or WAIT mode. This pin is not
available in the 48 / 52 pin package versions.
2.3.18 PP[6] / KWP[6]/ROMCTL — Port P I/O Pin [6]
PP6 is a general purpose input or output pin, shared with the keypad interrupt function. When configured
as an input, it can generate interrupts causing the MCU to exit STOP or WAIT mode. This pin is not
available in the 48 / 52 pin package versions. During MCU expanded modes of operation, this pin is used
to enable 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.
PP6=1 in emulation modes equates to ROMON =0
(ROM space externally mapped)
PP6=0 in expanded modes equates to ROMON =0 (ROM space externally mapped)
2.3.19 PP[5:0] / KWP[5:0] / PW[5:0] — Port P I/O Pins [5:0]
PP[5:0] are general purpose input or output pins, shared with the keypad interrupt function. When
configured as inputs, they can generate interrupts causing the MCU to exit STOP or WAIT mode.
PP[5:0] are also shared with the PWM output signals, PW[5:0]. Pins PP[2:0] are only available in the 80
pin package version. Pins PP[4:3] are only available in the 52 and 80 pin package version.
2.3.20 PJ[7:6] / KWJ[7:6] — Port J I/O Pins [7:6]
PJ[7:6] are general purpose input or output pins, shared with the keypad interrupt function. When
configured 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.
