Description
Code Violations
If the HDB3 or the CMI code with HDB3-precoding is selected, the 16-bit
counter is incremented when violations of the HDB3 code are detected.
The error detection mode is determined by programming the bit
MR0.EXTD. If simple AMI coding is enabled (MR0.RC(1:0) = ´01
bipolar violations are counted. The error counter does not roll over.During
alarm simulation, the counter is incremented every four bits received up
to its saturation. Clearing and updating the counter is done according to
bit MR1.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 is stopped
and the error counter is reset. Bit DEC.DCVC is reset automatically with
reading the error counter high byte. If MR1.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.
