8.12.1
PGDDR specifies input or output for the pins of the port G.
Since PGDDR is a write-only register, the bit manipulation instructions must not be used to write
PGDDR. For details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.
Notes: 1. The initial value becomes 1 in modes 4 and 5 and 0 in modes 6 and 7.

Modes 4 to 6:
Setting a PGDDR bit to 1 makes the PG4 to PG1 pins bus
control signal output pins, while clearing the bit to 0
makes the pins input ports.
Mode 7:
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.
(H8S/2212 Group)
Setting a PG1DDR bit to 1 makes the corresponding port
G pin an output port, while clearing the bit to 0 makes the
pin an input port.
(H8S/2212 Group)
When EMLE = 1: Pin PG0 function as the H-UDI (TDI)
pin.
When EMLE = 0: If a PG0DDR bit is set to 1, pin PG0
function as output ports. If a PG0DDR bit is cleared to 0,
pin PG0 function as input ports.
