6.2.6 ALTERNATIVE CE#-CONTROLLED WRITES
NOTES:
1. In systems where CE# defines the write pulse width (within a longer WE# timing waveform), all setup, hold, and inactive
2. Sampled, not 100% tested.
3. Refer to Table 4 for valid A
4. V
5. If BYTE# switch during reading cycle, exist the regulations separately.
