RSC

Received Signaling Information Changed

This interrupt bit is set during each multiframe in which signaling

information on at least one channel changes its value from the

previous multiframe. This interrupt only occurs in the synchronous

state. The registers RS(12:1) should be read within the next 3 ms

otherwise the contents is lost.

CRC6

Receive CRC6 Error

0 =

No CRC6 error occurs.

1 =

The CRC6 check of the last received multiframe failed.

PDEN

Pulse-Density Violation

The pulse-density violation of the received data stream defined by

ANSI T1. 403 is violated. More than 14 consecutive zeros or less than

N ones in each and every time window of 8

×(N+1) data bits (N = 23)

are detected. If GCR.SCI is set high this interrupt status bit is

activated with every change of state of FRS1.PDEN.

RPF

Receive Pool Full - HDLC Channel 1

32 bytes of a frame have arrived in the receive FIFO. The frame is not

yet received completely.
