Notes 1. HS is condition of HS (high-speed main) mode.
2. LS is condition of LS (low-speed main) mode.
3. LV is condition of LV (low-voltage main) mode.
4. 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.
5. 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.
6. 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), m: Unit number (m = 0), n: Channel number (n = 0),
g: PIM and POM numbers (g = 1)

(Operation clock to be set by the CKSmn bit of serial mode register mn (SMRmn). m: Unit number,
n: Channel number (mn = 00))
