CRC Errors
No function if doubleframe format is selected.
In CRC-multiframe mode, the 16-bit counter will be incremented
when a CRC-submultiframe has been received with a CRC error.
CRC errors will not be counted during asynchronous state.
During alarm simulation, the counter is incremented once per
submultiframe up to its saturation.
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.DCEC1
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.DCEC1 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.
