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.
1.7.2.13 PP[7:0] / KWP[7:0] — Port P I/O Signals
PP[7:0] are general-purpose input or output signals. The signals can be configured on per signal basis as
interrupt inputs with wakeup capability (KWP[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 disabled .
1.7.2.14 PS[7:0] — Port S I/O Signals
PS[7:0] 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-up devices are enabled. The signals can be configured
on per pin basis in open-drain mode.
