Notes  1. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp 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 pin and the normal output mode for the SOp pin and 
SCKp pin by using port input mode register g (PIMg) and port output mode register g (POMg). 
Remarks 1.  p: CSI number (p = 00, 01, 10, 11, 20, 21, 30, 31), m: Unit number (m = 0, 1), n: Channel number (n = 0
