17.2.10
When the CKP bit is cleared, the SCL output is held low
once it is sampled low. Therefore, the CKP bit will not
stretch the SCL line until an external I
has already asserted the SCL line low. 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 (Figure 17-14).
