SSIp setup time tSSIK DAP = 0 120 ns
DAP = 1 1/fMCK + 120 ns
SSIp hold time tKSSI DAP = 0 1/fMCK + 120 ns
DAP = 1 120 ns
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.
4. C is the load capacitance of the SCKp and SOp output lines.
Caution Select the normal input buffer for the SIp, SCKp and SSIp pins and normal output mode and special
slew rate for the SOp pin.
Remarks 1. p: CSIp (p = 00, 01, 10, 11), m: Unit m (m = 0, 1), n: Channel n (n = 0, 1)
2. f
MCK: Serial array unit operation clock frequency
