1.
If the S1D13505 host interface is disabled, the timing for CARDxWAIT* driven is relative to
the falling edge of chip select or the second positive edge of DCLKOUT after ADDR[12:0]
becomes valid, whichever one is later.
2.
If the S1D13505 host interface is disabled, the timing for D[31:16] driven is relative to the
falling edge of chip select or the second positive edge of DCLKOUT after ADDR[12:0] be-
comes valid, whichever one is later.
Note
The Toshiba interface has different clock input requirements as follows:
