Notes

5.While there are 20 address lines on the CY14B108L (19 address lines on the CY14B108N), only the 13 address lines (A14 - A2) are used to control software modes. Rest of the address lines are don’t care.

6.The six consecutive address locations must be in the order listed. WE must be HIGH during all six cycles to enable a nonvolatile cycle.
