Description
Y SWIOP These bits can be individually programmed as input (with selectable
pull-up resistor), output (with selectable drive strength), or external
interrupt (with selectable assertion level). Each GPIO input pin is
latched at the beginning of a read cycle.
Y IOHPP These bits can be individually programmed as input (with selectable
H
pull-up resistor) or output (with selectable drive strength). Each
MPIO input pin is latched at the beginning of a read cycle.
