NOTES:
1. X = Don’t Care. 1 = logic high. 0 = logic low.
2. Write is defined as either 1) any SBx and SW low or 2) SGW is low.
3. G is an asynchronous signal and is not sampled by the clock K. G drives the bus immediately (tGLQX) following G going low.
4. On write cycles that follow read cycles, G must be negated prior to the start of the write cycle to ensure proper write data setup times. G must
also remain negated at the completion of the write cycle to ensure proper write data hold times.
5. This READ assumes the RAM was previously deselected.
