Product Specification (V1.0) 09.05.2005
(This specification is subject to change without further notice)
8.2.19 Extended Power Control
(At the time of reset: {DIS} = 0H, {BF1, BF0}=0H; read address: 9H)
The DIS register controls the capacitors (connected between the power supply V0-V4
for LCD drive voltage and VSS) discharge.
When using this register, refer to Section 7-22 (Discharge Circuit).
DIS = “0”: Discharge OFF
DIS = “1”: Discharge start
BF1~BF0: Select the operating frequency in the booster. When the boosting frequency
is high, the driving ability of the booster becomes high, and the power consumption is
increased. When you adjust the boosting frequency, you must take into considerations
the external capacitors and the current consumption.
8.2.20 Window End X Address
(At the time of reset: {EX3, EX2, EX1, EX0} = 0H, read address: AH)
(At the time of reset: {EX7, EX6, EX5, EX4} = 0H, read address: BH)
The EX registers set the X direction end address for the window function.
8.2.21 Window End Y Address
(At the time of reset: {EY3, EY2, EY1, EY0} = 0H, read address: CH)
(At the time of reset: {EY6, EY5, EY4} = 0H, read address: DH)
The EY registers set the Y direction end address for the window function.
