Notes 1. Can be set as port function.

2. To use P60/SCK11/SCLA0/INTP11 as port pins, clear CKP11 to 0.

3. To use the slave mode, set CKS112, CKS111, and CKS110 to 1, 1, 1.

Remarks 1. ×: don’t care

CSIE11: Bit 7 of serial operation mode register 11 (CSIM11)

TRMD11: Bit 6 of CSIM11

CKP11: Bit 4 of serial clock selection register 11 (CSIC11)

CKS112, CKS111, CKS110: Bits 2 to 0 of CSIC11

PM×: Port mode register

P×: Port output latch

2. The SSI11 pin is available only in 48-pin products of 78K0/KC2-L.
