Pulse Density Violation Detector (PDVD)  
The Pulse Density Violation Detection function is provided by the PDVD block.  
This block detects pulse density violations of the ANSI T1.403 requirement that  
there be N ones in each and every time window of 8(N+1) data bits (where N can  
equal 1 through 23). The PDVD also detects periods of 16 consecutive zeros in  
the incoming data. Pulse density violation detection is provided through an  
internal register bit. An interrupt is generated to signal a 16 consecutive zero  
event or a change of state on the pulse density violation indication.
