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

remain low until the CKP bit is set and all other
devices on the I

minimum high time requirement for SCL (see
