Notes
6. BHE
and BLE are applicable for × 16 configuration only.
7. While there are 20 address lines on the CY14B108K (19 address lines on the CY14B108M), only the 13 address lines (A
14
–A
2
) are used to control software modes.
The remaining address lines are don’t care.
8. The six consecutive address locations must be in the order listed. WE
must be HIGH during all six cycles to enable a nonvolatile cycle.
