Notes:
1. There is a 6 RCLK delay from RPOS, RNEG to RSER
2. RCHBLK is programmed to block channel 2
3. RLINK is programmed to output the Sa4 bit
4. Shown is a non-align frame boundary
5. RSIG normally contains the CAS multiframe alignment nibble (0000) in Channel 1

Notes:
1. RSYNC in the frame mode (RCR1.6 = 0)
2. RSYNC in the multiframe mode (RCR1.6 = 1)
3. RLCLK is programmed to output just the Sa4 bit
4. RLINK will always output all five Sa bits as well as the rest of the receive data stream
5. This diagram assumes the CAS MF begins with the FAS word
