Port G Register (PORTG)
Note: * Determined by state of pins PG
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.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.
