1. If the S1D13505 host interface is disabled, the timing for WAIT# driven is relative to the fall-ing edge of CSn# or the first positive edge of CKIO 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 RD# or the first positive edge of CKIO after A[20:0], M/R# becomes valid,whichever one is later.
