Notes 1. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The Slp setup time becomes "to
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 SIp hold time becomes "from
SCKp" when DAPmn = 0 and CKPmn = 1 or DAPmn = 1 and CKPmn = 0.
3. 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.
