only active during FMR0.SIM = 1
FEC is counting +2 while EBC is counting +1 if the framer is in synchronous state; if asynchronous in state 2
but synchronous in state 6, counters are incremented during state 6

Alarm Simulation States
Error Simulation Counter
This three-bit counter is incremented by setting bit FMR0.SIM. The
state of the counter determines the function to be tested.
For complete checking of the alarm indications, eight simulation steps
are necessary (FRS2.ESC = 0 after a complete simulation).
