Serial Interface Part
Notes: 1. AC characteristics are measured at 150 pF capacity load as an output load based on 0.8 V at
low level and 2.2 V at high level for output and 1.5 V for input.

4. This recovery time is mode Initialization only. Recovery time between command writes for
Asynchronous Mode is 8 t
CY
and for Synchronous Mode is 18 t
CY
.
Write Data is allowed only when TXRDY = 1.
5. This recovery time is Status read only.
Read Data is allowed only when RXRDY = 1.
6. Status update can have a maximum delay of 28 clock periods from event affecting the status.
Max.
