Port G Data Register (PGDR)
PGDR is an 8-bit readable/writable register that stores output data for the port G pins (PG
PG
Bits 7 to 5 are reserved; they return an undetermined value if read, and cannot be modified.
PGDR is initialized to H'00 (bits 4 to 0) by a power-on reset, and in hardware standby mode. It
retains its prior state after a manual reset, and in software standby mode.

to 1, and as an input port when the bit is cleared to 0.
For pins PG
while clearing the bit to 0 makes the pin an input port.
Modes 3 and 7 [H8S/2351 only]
Setting a PGDDR bit to 1 makes the corresponding port G pin an output port, while clearing
the bit to 0 makes the pin an input port.
Modes 4 and 5 [H8S/2350]; modes 4, 5, and 6 [H8S/2351]
Pins PG
PGDDR bits are set to 1, and as input ports when the bits are cleared to 0.
Pin PG
setting the corresponding PGDDR bit to 1 makes the pin an output port, while clearing the bit
to 0 makes the pin an input port. For details of the DRAM interfaces, see section 6, Bus
