Hardware Functional Specification S1D13505
Issue Date: 01/02/02 X23A-A-001-14
1. If the S1D13505 host interface is disabled, the timing for WAIT# driven low is relative to the
falling edge of RD0#, RD1#, WE0#, WE1# or the first positive edge of CLK after A[20: 0 ] ,
M/R# becomes valid, whichever one is later.
2. If the S1D13505 host interface is disabled, the timing for D[15:0] driven is relative to the fall-
ing edge of RD0#, RD1# or the first positive edge of CLK after A[20:0], M/R# becomes valid,
whichever one is later.
