10.4.5 Output pins

(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
1
Remarks 1. n = 0, 1
2. When any of bits CKP and CKS2 to CKS0 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
1
Remarks 1. n = 0, 1
2. When any of bits TRMDn, CCL, DIRn, and AUTO of the CSIMn register or DAP bit of the
CSICn register is overwritten, the SOn pin output changes.
3. SOTBm: Bit m of SOTBn register (m = 0, 7, 15)
4. SOTBFm: Bit m of SOTBFn register (m = 0, 7, 15)
