Counter Mode
This bit selects the alarm timer mode. If counter mode is set to
multiframes (‘0’) the value in CV determines the number of multiframes
after which the TE3-CHATT declares AIS or RED. When counter mode
is set to ‘½ milliseconds’ (‘1’) the value in CV determines the time in CV
x 0.5 ms after which AIS or RED is declared.
