RFP
Output
Receive Frame Pulse (RFP). When
the E1XC is configured for receive
frame pulse output, RFP pulses high
for 1 RCLKO cycle during bit 1 of each
256-bit frame, indicating the frame
alignment of the RDPCM data stream.
When configured for receive signalling
multiframe output, RFP pulses high for
1 RCLKO cycle during bit 1 of frame 1
of the 16 frame signalling multiframe,
indicating the signalling multiframe
alignment of the RDPCM data stream.
(Even when signalling multiframing is
disabled, the RFP output continues to
indicate the position of bit 1 of every
th
16 frame.)
When configured for receive CRC
multiframe output, RFP pulses high for
1 RCLKO cycle during bit 1 of frame 1
of every 16 frame CRC multiframe,
indicating the CRC multiframe
alignment of the RDPCM data stream.
(Even when CRC multiframing is
disabled, the RFP output continues to
indicate the position of bit 1 of the
th
FAS frame every 16 frame.)
