Port Control
PT2-0:
Controls the output level of a port output pin (PORT2-PORT0). When PT0 = 0, it specifies the
POT0 output to GND and when PT0 = 1, to VCC. Similarly, PT1 and PT2 bits control PORT1 and PORT2
output levels respectively.

RAM Address Set
RM1-0:
Selects DDRAM, CGRAM, and SEGRAM. The selected RAM is accessed with this setting.
AD9-0:
Initially sets RAM addresses to the address counter (AC). Once RAM data is accessed, the AC is
automatically updated according to the I/D bit. This allows consecutive accesses without resetting
addresses. RAM address setting is not allowed in the sleep mode or standby mode.
