• Manufacturer Part Number: EM65101AF
• Description: 128COM/160SEG 16 Gray Scale Level LCD Driver
• Manufacturer: EMC [ELAN Microelectronics Corp]

Product Specification (V0.4) 08.15.2005
(This specification is subject to change without further notice)
DCON: This command sets the internal booster circuit ON or OFF.
DCON = “0”: Booster circuit OFF
DCON=”1”: Booster circuit ON
ACL: This command initializes the internal circuit.
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 display. Therefore, set the WAIT period
to at least two display clock cycles. After the WAIT period, the subsequent operation is
then executed.
8.2.8 LCD Duty (DS)
(At the time of reset: {DS3, DS2, DS1, DS0} = 0H, read address: 9H)
(At the time of reset: {DS7, DS6, DS5, DS4} = 8H, read address: AH)
The DS register set to LCD display duty.
Partial display can be made possible by setting an arbitrary duty ratio.
