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 becomes “to 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 SIp hold time becomes “from SCKp

↓”

when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.

4. 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.

Caution

Select the TTL input buffer for the SIp pin and SCKp pin and the N-ch open drain output (VDD tolerance

(for the 20- to 52-pin products)/EVDD tolerance (for the 64- to 128-pin products)) mode for the SOp pin by

using port input mode register g (PIMg) and port output mode register g (POMg). For VIH and VIL, see the

DC characteristics with TTL input buffer selected.

2. p: CSI number (p = 00, 01, 10, 20, 30, 31), m: Unit number (m = 0, 1), n: Channel number (n = 00, 01, 02,

10, 12, 13), g: PIM and POM number (g = 0, 1, 4, 5, 8, 14)

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, 01, 02, 10, 12, 13))

4. CSI01 of 48-, 52-, 64-pin products, and CSI11 and CSI21 cannot communicate at different potential. Use

other CSI for communication at different potential.
