When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp setup time becomes âto
SCKpââ when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp hold time becomes âfrom
SCKpââ when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The delay time to SOp output
becomes âfrom SCKpââ when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
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 and SCKp pins
by using port input mode register 1 (PIM1) and port output mode registers 0, 1, 4 (POM0, POM1,
POM4).
Remarks 1. p: CSI number (p = 00, 01, 11, 20), m: Unit number (m = 0, 1), n: Channel number (n = 0, 1, 3)
2. fMCK: 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 (m = 0, 1), n: Channel number (n = 0, 1, 3))
