Note 1.

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

Note 2.

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

Caution

Select the TTL input buffer for the SIp pin and the N-ch open drain output (VDD tolerance (for the 30- to 52-pin

products)/EVDD tolerance (for the 64- to 100-pin products)) mode for the SOp pin and SCKp 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.

Remark 1.

Rb[

Ω]: Communication line (SCKp, SOp) pull-up resistance, Cb[F]: Communication line (SCKp, SOp) load capacitance,

Vb[V]: Communication line voltage

Remark 2.

p: CSI number (p = 00), m: Unit number (m = 0), n: Channel number (n = 0), g: PIM and POM number (g = 3, 5)

Remark 3.

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))

Remark 4.

This value is valid only when CSI00’s peripheral I/O redirect function is not used.

Communication at different potential (2.5 V, 3 V) (CSI mode) (master mode, SCKp... internal clock output,

corresponding CSI00 only)
