Device Overview MC9S12G-Family
1.7.2.4 EXTAL, XTAL — Oscillator Signal
EXTAL and XTAL are the crystal driver and external clock signals. On reset all the device clocks are
derived from the internal reference clock. XTAL is the oscillator output.
1.7.2.5 PAD[15:0] / KWAD[15:0] — Port AD Input Pins of ADC
PAD[15:0] are general-purpose input or output signals. These signals can have a pull-up or pull-down
device selected and enabled on per signal basis. Out of reset the pull devices are disabled.
1.7.2.6 PA[7:0] — Port A I/O Signals
PA[7:0] are general-purpose input or output signals. The signals can have pull-up devices, enabled by a
single control bit for this signal group. Out of reset the pull-up devices are disabled .
1.7.2.7 PB[7:0] — Port B I/O Signals
PB[7:0] are general-purpose input or output signals. The signals can have pull-up devices, enabled by a
single control bit for this signal group. Out of reset the pull-up devices are disabled .
1.7.2.8 PC[7:0] — Port C I/O Signals
PC[7:0] are general-purpose input or output signals. The signals can have pull-up devices, enabled by a
single control bit for this signal group. Out of reset the pull-up devices are disabled .
1.7.2.9 PD[7:0] — Port D I/O Signals
PD[7:0] are general-purpose input or output signals. The signals can have pull-up device, enabled by a
single control bit for this signal group. Out of reset the pull-up devices are disabled.
1.7.2.10 PE[1:0] — Port E I/O Signals
PE[1:0] are general-purpose input or output signals. The signals can have pull-down device, enabled by a
single control bit for this signal group. Out of reset the pull-down devices are enabled.
1.7.2.11 PJ[7:0] / KWJ[7:0] — Port J I/O Signals
PJ[7:0] are general-purpose input or output signals. The signals can be configured on per signal basis as
interrupt inputs with wakeup capability (KWJ[7:0]). They can have a pull-up or pull-down device selected
and enabled on per signal basis. Out of reset the pull devices are enabled .
1.7.2.12 PM[3:0] — Port M I/O Signals
PM[3:0] are general-purpose input or output signals. They can have a pull-up or pull-down device selected
and enabled on per signal basis. Out of reset the pull devices are disabled. The signals can be configured
on per pin basis to open-drain mode.
