NOTES:
1. True (T) is SE =1 and SE =o.
2. Registered inputs (Addresses, SW, SE, and SE) satisfy the specified setup and hold times about the rising edge of clock
(K). Data-in satisfies the specified setup and hold times for DL.
3. A transparent write cycle is defined by DL high during the write cycle.
4. A latched write cycle is defined by DL transitioning low during the write cycle and satisfying the specified setup and
hold times.
