Notes 1.  Transfer rate in the SNOOZE mode : MAX. 1 Mbps 
 2.  When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1.  The SIp setup time or 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 SOp output lines. 
 
Caution  Select the normal input buffer for the SIp pin and SCKp pin and the normal output mode for the SOp pin 
by using port input mode register g (PIMg) and port output mode register g (POMg).
