Code Violations
No function if NRZ Code has been enabled.
If the B8ZS code (bit FMR0.RC1/0 = 11) is selected, the 16-bit
counter will be incremented by detecting violations which are not due
to zero substitution. If FMR2.EXZE is set, additionally excessive zero
strings (more than 7 contiguous zeros) are detected and counted.
If simple AMI coding is enabled (FMR0.RC0/1 = 10) all bipolar
violations are counted. If FMR2.EXZE is set, additionally excessive
zero strings (more than 15 contiguous zeros) are detected and
counted.
During alarm simulation, the counter is incremented continuously with
every second received bit.
Clearing and updating the counter is done according to bit
FMR1.ECM.
If this bit is reset the error counter is permanently updated in the
buffer. For correct read access of the error counter bit DEC.DCVC
has to be set. With the rising edge of this bit updating the buffer will
be stopped and the error counter will be reset. Bit DEC.DCVC will
automatically be reset with reading the error counter high byte.
If FMR1.ECM is set every second (interrupt ISR3.SEC) the error
counter will be latched and then automatically reset. The latched error
counter state should be read within the next second.
