Input/Output (I/O) Ports
When bit DDRFx is a 1, reading address $0440 reads the PTFx data latch. When bit DDRFx is a 0,
reading address $0440 reads the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
13.9 Port G
Port G is an 8-bit special-function port that shares all eight of its pins with the analog-to-digital converter
(ADC) module.
13.9.1 Port G Data Register
The port G data register (PTG) contains a data latch for each of the eight port pins.

Alternate Function:
1. X = Don’t care
2. Hi-Z = High impedance
3. Writing affects data register, but does not affect input.
