Note 4)

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).
