8.2.7 Power Control Register
(At the time of reset: {AMPON, HALT, DCON, ACL} = 0H, read address: 9H)
„ ACL
The internal circuit can be initialized as follows:
ACL = “0”: Normal operation
ACL = “1”: Initialization ON
When the reset operation begins internally after the ACL register is set to “1,” the ACL
register is automatically cleared to “0.” The internal reset signal is generated with a
clock (built-in oscillation circuit or CK input) for the display. Therefore, install at least
two cycles for the WAIT period for the clock display. After the WAIT period elapsed, the
next operation is processed.
„ DCON
Sets ON/OFF the internal booster circuit:
DCON = “0”: Booster circuit OFF
DCON = ”1”: Booster circuit ON

When gradation display mode and 8-bit access are selected, address is
incremented as described above.
When gradation display mode and 16-bit access are selected, the following
increment processing occurs:
1) Accessing the RAM after every two bytes are accessed.
2) The X-addresses increments in the order of 00H, 01H,…2FH, and 30H.
