Test Conditions
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.
