15.4.4.5
If a user clears the CKP bit, the SCL output is forced to
‘0’. Setting the CKP bit will not assert the SCL output
low until the SCL output is already sampled low. If the
user attempts to drive SCL low, the CKP bit will not
assert the SCL line until an external I
has already asserted the SCL line. The SCL output will
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 SCL (see
Figure 15-12).
