Transmit and receive CMI is enabled through OUTAC.7. When this register bit is set, the TTIP pin
outputs CMI-coded data at normal TTL-type levels. This signal can be used to directly drive an optical
interface. When CMI is enabled, the user can also use HDB3 coding.
When this register bit is set, the RTIP pin becomes a unipolar CMI input. The CMI signal is processed to
extract and align the clock with data. The BPV counts CVs (code violations) in the CMI signal. CVs are
defined as consecutive ones of the same polarity as shown in
Figure
17-2. If HDB3 precoding is enabled,
then the CVs generated by HDB3 are not counted as errors.
