*1: Low = Input Low Voltage = V_IL(<0.8V)
*2: High = Input High Value = VIL(>2.0V)
*3: In Gang Write Mode, All OTPs are programmed sim-
ulaneously. So all signals of OTPs are in the same condi-
tion
*4: In Gang Verify mode, the VPP pin can be sset to both
normal high(5V), aand 12.75V and chip slecection is pos-
sible using the CEB pin
