CGRAM data: logic 1 of a data bit turns the icon on and logic 0 turns the icon off.

Character codes: bits 0 to 3 define the icon state when icon blink is disabled or during the even phase when icon blink is

enabled. Bits 4 to 7 define the icon state during the odd phase when icon blink is enabled (not used for icons when icon blink is

disabled)

Product data sheet

Bit DM: When DM = 0, the chip is not in the direct mode. Either the internal VLCD

generator or an external voltage may be used to achieve VLCD.

When DM = 1, the chip is in direct mode. The internal VLCD generator is turned off and the

output VLCDOUT is directly connected VDD2 (i.e. the VLCD generator supply voltage).
