Figure 7-10. ICG Module I/O Register Summary
for method of clearing the CMF bit.
The ICG contains five registers, summarized in
registers are:
Several of the bits in these registers have interaction where the state of
one bit may force another bit to a particular state or prevent another bit
from being set or cleared. A summary of this interaction is shown in
