Function setting using command input (user settings)
Setting voltage V1 adjustment internal resistor ratio *6
Electronic potentiometer
*7
Power save OFF
*9
Function setting using command input (user settings)
*(b)
Power control set
*8
Wait for more than 300 ms
*(c)
Initial setting state complete
*(a): Enter the power save state within 5ms after releasing the reset state.
*(b): Carry out power control set within 5ms after releasing the power save state.
The 5ms duration in *(a) and *(b) changes depending on the panel characteristics and the value of
the smoothing capacitor. We recommend verification of operation using an actual unit.
*(c): When trace resistance in COG mounting does not exist, wait for over 300 ms.
Since this value varies with trace resistance, V1, smoothing capacitors, or voltage multiplier
capacitors in COG mounting, confirm operation on an actual circuit board when using this LSI.
