Notes:
1. RSYNC in the frame mode (RCR2.4 = 0) and double-wide frame sync is not enabled (RCR2.5 = 0)
2. RSYNC in the frame mode (RCR2.4 = 0) and double-wide frame sync is enabled (RCR2.5 = 1)
3. RSYNC in the multiframe mode (RCR2.4 = 1)
4. RLINK data (Fs - bits) is updated one bit prior to even frames and held for two frames
5. RLINK and RLCLK are not synchronous with RSYNC when the receive side elastic store is enabled
