NOTES :
1. In systems where CE# defines the write pulse width
(within a longer WE# timing waveform), all setup, hold,
and inactive WE# times should be measured relative to
the CE# waveform.
2. Sampled, not 100% tested.
3. Refer to Table 3 for valid AIN and DIN for block erase or
word write.
4. VPP should be held at VPPH1/2/3 (and if necessary RP#
should be held at VHH) until determination of block erase
or word write success (SR.1/3/4/5 = 0 : on Boot Blocks,
SR.3/4/5 = 0 : on Parameter Blocks and Main Blocks).
