35.1 T1 Mode
Figure 35-1. Receive-Side D4 Timing
Note 1: RSYNC in the frame mode (IOCR1.5 = 0) and double-wide frame sync is not enabled (IOCR1.6 = 0).
Note 2: RSYNC in the frame mode (IOCR1.5 = 0) and double-wide frame sync is enabled (IOCR1.6 = 1).
Note 3: RSYNC in the multiframe mode (IOCR1.5 = 1).
Note 4: RLINK data (Fs bits) is updated one bit prior to even frames and held for two frames.
