11. Initialization of LCM
The LCM automatically initializes ( reset ) when power is turned on using the internal reset circuit. If the power supply
conditions for correctly operating of the internal reset circuit are not met, initialization by instruction is required. Use the
procedure is next page for initialization.
Internal Power Supply reset
4.5V
Vcc 0.2V
toff
trcc - - - - - -
(Note 1) 10 ms ? trcc ? 0.1 ms , toff ? 1 ms.
(Note 2) toff stipulates the time of power OFF for momentary power supply dip or when power supply cycles ON and OFF.
