Note 1)
The output polarity of SDIBCK and SDOBCK can be changed by DSIBP and DSOBP. In the
figure below, SDOBP = SDOBP = 0.
Note 2)
Although output divided from SDIMCK can be selected for SDOBCK via WBSEL[2:0], operation
is not guaranteed if SDIMCK’s frequency exceeds the range noted above.
Note 3)
When “SDIBCK through” has been selected (WBSEL[2:0] = 00), the SDDBCK output duty factor
is affected by the SDIBCK duty factor.
Note 4)
When “SDIBCK through” has been selected (WBSEL[2:0] = 00).
