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.
