WRITE CYCLE 2 (/OE Low Fixed)
Notes (WRlTE CYCLE):
1. A write occurs during the overlap of a low /CS and a low /WE. A write begins at
the latest transition among /CS going low and /WE going low: A write ends at
the earliest transition among /CS going high and /WE going high. t
WP
is
measured from the beginning of write to the end of write.
2. tcw is measured from the later of /CS going low to the end of write .
3. t
AS
is measured from the address valid to the beginning of write.
4. t
WR
is measured from the end of write to the address change. t
WR
is applied in
case a write ends as /CS, or /WE going high.
5. If /OE and /WE are in the read mode during this period, and the I/O pins are in
the output low-Z state, input of opposite phase of the output must not be applied
because bus contention can occur.
6. If /CS goes low simultaneously with /WE going low, or after /WE going low,
the outputs remain in high impedance state.
7. D
OUT
is the same phase of latest written data in this write cycle.
8. D
OUT
is the read data of the new address.
