4.0 Registers
4.1 Registers
0x47—RXPTH (Receive Path Overhead Status Register)
The RXPTH register contains status information for the receiver Path Overhead.
0x6B—RXPTHBUF (Receive Path Trace Circular Buffer, J1)
The RXSECBUF buffer is used to receive repeatedly a 64-byte, fixed-length string so that a receiving terminal
in a path can verify its continued connection to the intended transmitter.
