(1) SCKn pin
When the CSIn operation is disabled (CSICAEn bit of CSIMn register = 0), the SCKn pin output status is as
follows (n = 0, 1).
CKP
0

Remarks 1. n = 0, 1
2. When any of the CKP and CKS2 to CKS0 bits of the CSICn register is overwritten, the SCKn
pin output changes.
(2) SOn pin
When the CSIn operation is disabled (CSICAEn bit of CSIMn register = 0), the SOn pin output status is as
follows (n = 0, 1).
TRMDn DAP
0 Don't care
1 0
