SLP:
When SLP = 1, the HD66789 enters into the sleep mode. In the sleep mode, internal display
operation is halted except the R-C oscillator to reduce current consumption. Only power control
instructions
(BT2–0, DC2–0, AP2–0, SLP, STB, VC2-0, VRH4-0, VCOMG, VDV4-0, and VCM4-0 bits) are executed
during the sleep mode. No change is made to the GRAM data or instructions during the sleep mode,
although it is retained.
STB:
When STB = 1, the HD66789 enters into the standby mode. In the standby mode, display operation
is completely halted, and all internal operation including the internal R-C oscillator and reception of
external clock pulse, is halted. For details, see the “Standby Mode” section. Only instructions to release
the standby mode (STB = 0) and to start oscillation are accepted during the standby mode. Changes in the
GRAM data or instructions during the standby mode are susceptible to destruction. These changes should
be made after releasing the standby mode.
VC2-0:
Adjust the reference voltage for VREG1OUT, VciOUT voltages to the optimum ratio of Vci.
