10.15.2 Port G Data Register (PGDR)
PGDR stores output data for the port G pins.
Bit Bit Name Initial Value R/W Description
7 ⎯ 0 ⎯ Reserved
This bit is always read as 0, and cannot be modified.
6 PG6DR 0 R/W
5 PG5DR 0 R/W
4 PG4DR 0 R/W
3 PG3DR 0 R/W
2 PG2DR 0 R/W
1 PG1DR 0 R/W
An output data for a pin is stored when the pin
function is specified to a general purpose I/O.
0 PG0DR 0 R/W
10.15.3 Port G Register (PORTG)
PORTG shows port G pin states.
PORTG cannot be modified.
Bit Bit Name Initial Value R/W Description
7 ⎯ Undefined ⎯ Reserved
If this bit is read, it will return an undefined value.
6 PG6 ⎯* R
5 PG5 ⎯* R
4 PG4 ⎯* R
3 PG3 ⎯* R
2 PG2 ⎯* R
1 PG1 ⎯* R
If a port G read is performed while PGDDR bits are
set to 1, the PGDR values are read. If a port G read
is performed while PGDDR bits are cleared to 0, the
pin states are read.
0 PG0 ⎯* R
Note: * Determined by the states of pins PG6 to PG0.
