Framing Errors
This 16-bit counter is incremented when a FAS word has been
received with an error.
Framing errors are counted during basic frame synchronous state
only (but even if multiframe synchronous state is not reached yet).
During alarm simulation, the counter is incremented every 250 s up
to its saturation. The error counter does not roll over.
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.DFEC has
to be set. With the rising edge of this bit updating the buffer is stopped
and the error counter is reset. Bit DEC.DFEC is reset automatically
with reading the error counter high byte.
If FMR1.ECM is set every second (interrupt ISR3.SEC) the error
counter is latched and then automatically reset. The latched error
counter state should be read within the next second.
