When the CKP bit is cleared, the SCLx output is forced
to ‘0’. However, clearing the CKP bit will not assert the
SCLx output low until the SCLx output is already
sampled low. Therefore, the CKP bit will not assert the
SCLx line until an external I

remain low until the CKP bit is set and all other
devices on the I
ensures that a write to the CKP bit will not violate the
minimum high time requirement for SCLx (see
