Acronyms:
PC – (Pullup/pulldown Controlled) Register controlled internal weak pullup/pulldown for a pin in the input mode. Refer to the
following sections for more information:
PD – (Pulldown) Internal weak pulldown for a pin in the input mode
DC – (Drive strength Controlled) Register controlled drive strength for a pin in the output mode. Refer to the following sections
for more information:
Z – Tristated pin
OD – (Open Drain) Output pin with open drain
Reset state:
All pins with the PC option – pullup/pulldown is disabled,
all pins with the DC option – have full drive strength
No load allowed except for bypass capacitors.
