Note:
1. The input test environment uses 0.1 VCC of overdrive over VIH and VIL. Timing parameters must
be met with no more overdrive than this. Vmax specifies the maximum peak-to-peak waveform
allowed for measuring the input timing. Production testing may use different voltage values, but
must correlate results back to these parameters.

1. There will be a 20-µs reset latency if a reset procedure is performed during a programming or
erase operation.
