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.
5. Transfer rate in the SNOOZE mode : MAX. 1 Mbps
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).
Remarks 1. p: CSI number (p = 00, 01), m: Unit number (m = 0),
n: Channel number (n = 0, 1), g: PIM number (g = 1)
2. f
MCK: Serial array unit operation clock frequency
(Operation clock to be set by the serial clock select register m (SPSm) and the CKSmn bit of serial mode
register mn (SMRmn). m: Unit number, n: Channel number (mn = 00, 01))
