Notes
1.
When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp setup time becomes “to SCKp
” and
the SIp hold time becomes “from SCKp
” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
2.
When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The delay time to SOp output becomes
“from SCKp
↑
” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
3.
C is the load capacitance of the SOp output lines.
4.
Transfer rate in the SNOOZE mode: MAX. 1 Mbps
