Section 9 I/O Ports
Port G Register (PORTG)
PORTG is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port G pins (PG
Bits 7 to 5 are reserved; they return an undetermined value if read, and cannot be modified.
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.
After a power-on reset and in hardware standby mode, PORTG contents are determined by the pin
states, as PGDDR and PGDR are initialized. PORTG retains its prior state after a manual reset,
and in software standby mode.
