*3 When the power is turned on, either the logic system power must be turned on before the LCD drive system
power or else they must both be turned on at the same time. When the power is turned off, either the LCD drive
system power must be turned off before the logic system power, or else both must be turned off at the same
time.
*4 The CP and LOAD rise time (tR) and the CP and LOAD fall time (tF) must satisfy equations (1) and (2) below
at the same time.

(2) tR, tF < 50ns
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
