1.
Any input used to select an internal PSD function.
2.
WR has the same timing as E, LDS, UDS, WRL, and WRH signals.
3.
tWHAX is 11 ns when writing to the output macrocell registers.
4.
tWHAX2 is the address hold time for DPLD inputs that are used to generate Sector Select signals for internal PSD memory.
5.
Assuming WRITE is active before data becomes valid.
6.
In multiplexed mode, latched address generated from ADIO delay to address output on any port.
7.
Assuming data is stable before active WRITE signal.
