Notes:
1. L = V
2. Address is A[17:0, -1] in Byte Mode and A[17:0] in Word Mode.
3. DQ[15] is the A[-1] input in Byte Mode (BYTE# = L).
Table 4. HY29LV400 Bus Operations Requiring High Voltage
Notes:
1. L = V
2. Address bits not specified are Don’t Care.
3. See text and for additional information.
4. SA = Sector Address. See Tables 1 and 2.
5. DQ[15] is the A[-1] input in Byte Mode (BYTE# = L).
6. Normal read, write and output disable operations are used in this mode. See Table 3.
