Caution

Select the normal input buffer for the SIp pin and SCKp pin and the normal output mode for the SOp pin by using

port input mode register g (PIMg) and port output mode register g (POMg).

Remark

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

(Slave Transmission of slave select input function (CSI00))

Remark 1.

p: CSI number (p = 00, 01, 10, 11, 20, 21, 30, 31)

Remark 2.

m: Unit number, n: Channel number (mn = 00 to 03, 10 to 13)
