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

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 (When 20- to

52-pin products)/EVDD tolerance (When 64- to 128-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.

Remarks 1. Rb[

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

capacitance, Vb[V]: Communication line voltage

2. p: CSI number (p = 00), m: Unit number (m = 0), n: Channel number (n = 0),

g: PIM and POM number (g = 1)

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))

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