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 (When 30- to 52-pin
products)/EV
DD tolerance (When 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 V
IH and VIL, see the DC characteristics
with TTL input buffer selected.
Remark 1.
Rb[]: Communication line (SCKp, SOp) pull-up resistance, Cb[F]: Communication line (SCKp, SOp) load capacitance,
V
b[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.
(7) Communication at different potential (2.5 V, 3 V) (CSI mode) (master mode, SCKp... internal clock output,
corresponding CSI00 only)
