Notes on command settings
1. RSTSYS: A command reset is executed immediately after the data is read.
The reset is cleared by returning the CS pin to high to reset this register. The reset is also cleared if this command is
executed consecutively or if this register is set to 0.
2. RAMCLR: The RAM can only be erased when display is off. This operation is not executed during display. This
operation cannot be executed if the LC oscillator is stopped. Only use this command when the LC oscillator is
operating.
This command bit is automatically cleared when the RAM erase operation completes.
Once the RAM erase command has been read in, the following time is required to complete the operation.
— Tclear = 5 [μs] + 4/f
OSC
(LC-oscillator)
×
288
3. OSCSTP: The LC oscillator stop command stops the LC oscillator connected to pins 2 and 3 (OSC
IN
and OSC
OUT
).
The oscillator stop command is only executed when display is off. It is not executed if display is in progress.
In external clock input mode, this command stops the acquisition of that clock signal.
4. TSTMOD: The test mode command is executed if the TEST
IN
pin (pin 5) is high. This command should not be used
by applications in normal operation.
Note: This register is set to 0 on a reset (either by the RST pin or by a command reset).

Normal operation
If CS is low, the reset is executed, but if
CS is high this command will be excluded.

The LC oscillator operating state is maintained.
Valid when the display is off. VRAM write
is not possible when the oscillator is
stopped.
