Notes:
1. Externally generated signal illustrates internal IMR+ chip clock phase relationship.
2. IMR+ chip standalone, X will be low. When attached to a HIMIB device, X reflects the state of the CI pair.
3. STR signal is not available when the IMR+ chip is attached to HIMIB device, and must be generated externally.
