Notes:
1. TA = 21
°C to 27°C, Vcc = 5.0V ± 10%.
2. COND ENABLE and COND DISABLE are generated and depend on the control signals on pins P2.6,
P2.7, P3.6 and P3.7. The signals set the device in to and out of different processing conditions, such
as programming condition, erasing condition, and verify condition.
