1. Typical figures are at 25 C and are for design aid only; not guaranteed and not subject to production
testing.
2. C
= 100pF on D0-D7, all other outputs are loaded with 50pF.
3. These times don't apply for Reset Register 0Ah, since RDY line goes low once during the cycle. Please
refer to Reset Operation and Host Mode sections for more information.
