Note 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.
Note 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.
Note 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.
Note 4. C is the load capacitance of the SOp output lines.
Note 5. The maximum transfer rate when using the SNOOZE mode is 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).
Remark 1.
p: CSI number (p = 00, 01, 10, 11, 20, 21, 30, 31), m: Unit number (m = 0, 1),
n: Channel number (n = 0 to 3), g: PIM number (g = 0, 1, 3 to 5, 14)
Remark 2. fMCK: Serial array unit operation clock frequency
(Operation clock to be set by the CKSmn bit of serial mode register mn (SMRmn). m: Unit number,
n: Channel number (mn = 00 to 03, 10 to 13))
(3) During communication at same potential (CSI mode) (slave mode, SCKp... external clock input)
