Write Timing
(3.0 V to 3.6 V Versions)
NOTES:
1. Any input used to select an internal PSD835G2 function.
2. In multiplexed mode, latched addresses generated from ADIO delay to address output on any Port.
3. WR timing has the same timing as E and DS signals.
4. Assuming data is stable before active write signal.
5. Assuming write is active before data becomes valid.
6. t
WHAX2
is Address hold time for DPLD inputs that are used to generate chip selects for internal PSD memory.
7.
t
WHDX
is 11ns when writing to the Output Micro
Cell Registers AB and BC.
