Chapter 6 Parallel Input/Output
6.3.6
Port F is an 8-bit port general-purpose I/O that is not shared with any peripheral module. Port F has high
current output drivers.
Port F pins are available as general-purpose I/O pins controlled by the port F data (PTFD), data direction
(PTFDD), pullup enable (PTFPE), and slew rate control (PTFSE) registers. Refer to
I/O
6.3.7
Port G is an 8-bit port which is shared among the background/mode select function, oscillator, and
general-purpose I/O. When the background/mode select function or oscillator is enabled, the pin direction
will be controlled by the module function.
Port G pins are available as general-purpose I/O pins controlled by the port G data (PTGD), data direction
(PTGDD), pullup enable (PTGPE), and slew rate control (PTGSE) registers. Refer to
I/O
The internal pullup for PTG0 is enabled when the background/mode select function is enabled, regardless
of the state of PTGPE0. During reset, the BKGD/MS pin functions as a mode select pin. After the MCU
is out of reset, the BKGD/MS pin becomes the background communications input/output pin. The PTG0
can be configured to be a general-purpose output pin. Refer to
Chapter 5, “Resets, Interrupts, and System
more information about using this pin.
The ICG module can be configured to use PTG2–PTG1 ports as crystal oscillator or external clock pins.
Refer to
oscillator pins.
