Data Sheet
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.
Receive CRC6 Error
0 =
1 =
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.
Receive Pool Full - HDLC Channel 1
32 bytes of a frame have arrived in the receive FIFO. The frame is not
yet received completely.
No CRC6 error occurs.
The CRC6 check of the last received multiframe failed.
