2.2.10 Port E input/Output (I/O) pins (PTE7–PTE0)
PTE7–PTE0 are general-purpose, bidirectional I/O port pins. These port pins also have
selectable pullup devices when configured for input mode, the pullup devices are
selectable on an individual port bit basis. The pulling devices are disengaged when
configured for output mode.
2.2.11 Port F input/output (I/O) pins (PTF7–PTF0)
PTF7–PTF0 are general-purpose, bidirectional I/O port pins. These port pins also have
selectable pullup devices when configured for input mode, the pullup devices are
selectable on an individual port bit basis. The pulling devices are disengaged when
configured for output mode.
2.2.12 Port G input/output (I/O) pins (PTG3–PTG0)
PTG3–PTG0 are general-purpose, bidirectional I/O port pins. These port pins also have
selectable pull-up devices when configured for input mode, the pullup devices are
selectable on an individual port bit basis. The pulling devices are disengaged when
configured for output mode.
2.2.13 Port H input/output (I/O) pins (PTH7–PTH6, PTH2–PTH0)
PTH7–PTH6, PTH2–PTH0 are general-purpose, bidirectional I/O port pins. These port
pins also have selectable pullup devices when configured for input mode, the pullup
devices are selectable on an individual port bit basis. The pulling devices are disengaged
when configured for output mode.
2.2.14 True open drain pins (PTA3–PTA2)
PTA3 and PTA2 operate in true open drain mode.
When configuring IIC to use SDA(PTA2) and SCL(PTA3)
pins, if an application uses internal pullups instead of external
pullups, the internal pullups remain present setting when the
