12.3.5 Output pins

(1) SCKn pin
When the CSIn operation is disabled (CSIE 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 (CSIE bit of CSIMn register = 0), the SOn pin output status is
as follows (n = 0, 1).
TRMD DAP
0 Don't care
1
Remarks: 1. When any of bits TRMD, CCL, DIR, AUTO, and CSICn of the CSIMn register or DAP bit
of the CSICn register is overwritten, the SOn pin output changes.
2. SOTBm: Bit m of SOTBn register (m = 0, 7, 15)
3. SOTBFm: Bit m of SOTBFn register (m = 0, 7, 15)
4. n = 0, 1
