retained.
STB: When STB = 1, the HD66750/1 enters the standby mode, where display operation completely stops,
halting all the internal operations including the internal R-C oscillator. Further, no external clock pulses
are supplied. For details, see the Standby Mode section.
Only the following instructions can be executed during the standby mode.
a. Standby mode cancel (STB = 0)
b. Start oscillation
c. Power control (BS2Ð0, BT1Ð0, DC1Ð0, AP1Ð0, SLP, and STB bits)
During the standby mode, the CGRAM data and instructions may be lost. To prevent this, they must be set
again after the standby mode is canceled.
