Input/
Receive Synchronization. If the receive-side elastic store is enabled, this signal
is used to input a frame or multiframe boundary pulse. If set to output frame
boundaries, RSYNCn can be programmed to output double-wide pulses on
signaling frames in T1 mode. In E1 mode, RSYNCn out can be used to indicate
CAS and CRC-4 multiframe. The DS26519 can accept an H.100-compatible
synchronization signal. The default direction of this pin at power-up is input, as
determined by the RSIO control bit in the RIOCR.2 register.
Receive Multiframe/Frame Synchronization 1 to 16. A dual function pin to
indicate frame or multiframe synchronization. RFSYNCn is an extracted 8kHz
pulse, one RCLKn wide that identifies frame boundaries. RMSYNCn is an
extracted pulse, one RCLKn wide (elastic store disabled) or one RSYSCLKn wide
(elastic store enabled), that identifies multiframe boundaries. When the receive
elastic store is enabled, the RMSYNCn signal indicates the multiframe sync on
the system (backplane) side of the elastic store. In E1 mode, this pin can indicate
either the CRC-4 or CAS multiframe as determined by the RSMS2 control bit in
the Receive I/O Configuration register (RIOCR.1).
