Standby Mode
Setting the standby mode bit (STB) to 1 puts the HD66726 in the standby mode, where the device stops
completely, halting all internal operations including the R-C oscillation circuit, thus further reducing
current consumption compared to that in the sleep mode. Specifically, character and segment displays,
which are controlled by the multiplexing drive method, are completely halted. Here, all the SEG (SEG1 to
SEG96) and COM (COM1 to COM40, COMS1/2) pins output the GND level, resulting in no display. If the
AMP bit is set to 0 in the standby mode, the LCD drive power supply can be turned off.
During the standby mode, no instructions can be accepted other than those for the start-oscillation
instruction and the key scan interrupt generation enable instruction. To cancel the standby mode, issue the
start-oscillation instruction to stabilize R-C oscillation before setting the STB bit to 0.
Although key scan is halted in the standby mode, the HD66726 can detect key inputs, thus generating key
scan interrupt (IRQ*). This means, the system can be activated from a completely inactive state. For
details, see the Key Scan Interrupt (Wake-up Function) section.
Set standby mode: STB = 1
Standby mode (Key scan interrupt enabled)
Issue the start-oscillation instruction
Wait at least 10 ms
Cancel standby mode: STB = 0
Turn on the LCD drive power supply: AMP = 1
Turn off the LCD power supply: AMP = 0
