NOTE:
DDRG[2:0] — Data Direction Register G Bits
Avoid glitches on port G pins by writing to the port G data register before
changing data direction register G bits from 0 to 1.
the port G I/O logic.
When DDRGx is a logic 1, reading address $000A reads the PTGx data
latch. When DDRGx is a logic 0, reading address $000A reads the
voltage level on the pin. The data latch can always be written, regardless
of the state of its data direction bit.
Table 17-6
Notes:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect the input.
These read/write bits control port G data direction. Reset clears
DDRG[2:0], configuring all port G pins as inputs.
