4.2.6 Standby register

This register is used to set or restore from a standby mode. The data set to bits 7 to 1 of this register is ignored.

When a standby command is input, the µPD161831 performs white display (source output, and VSS level output by

COMC) from the next frame following command output. Following the execution of this command, execute the

regulator OFF command and the DC/DC converter OFF for the power supply function. Also when standby is

canceled, doing the opposite of when standby is input, execute the normal operation command (R4 = “0”) after

setting both the DC/DC converter and the regulator to ON..

that must be input in 8-color mode differs depending on the selection of the 65,000-color mode and 260,000-color

transfer mode. For the actual data line to be used, refer to Table 4−4.

Note that the setting of this register is reflected from the operation of the next line after the register is set.
