Notes:
1. During this period, I/O pins are in the output state, so input signals of opposite phase to the outputs should not be applied.
2. The data output from D
OUT
are the same as the data written to D
IN
during the write cycle.
3. D
OUT
provides the read data for the next address.
4. Transition is measured
±
500 mV from steady state with C
L
= 5 pF. This parameter is guaranteed but not 100% tested.
