This command is for programming register DC[4:2].
When DC[2] is set to 0, the IC will put itself into Sleep mode. All drivers, voltage generation circuit and timing
circuit will be halted to conserve power. When DC[2] is set to 1, UC1682 will first exit from Sleep mode,
restore the power and then turn on COM drivers and SEG drivers. There is no other explicit user action or
timing sequence required to enter or exit the Sleep mode.
DC[3] controls the gray shade modulation modes. UC1682 has two gray shade modulation modes: an 8-
sahde mode and a 32-shade mode. The modulation curves are shown below. Horizontal axes are the gray
shade data. The vertical axes are the ON-OFF ratio. 9/9 is 100% ON for 8-shade mode, 51/51 is 100% ON
for 32-shade mode.
Revision 0.6
DC[4] enables dither function. Refer to (22) Set Color Mode for more information.
