RST: Hardware reset
The chip is forced to reset state if a low signal is input on this pin for more than 100ns.
0= short haul (10 dB)
1= long haul (36 dB for T1/J1, 43 dB for E1)
0= normal operation
1= receiver power down
00 = normal
01= All Ones
10= PRBS
11= transmitter power down
00 = JA is disabled
01 = JA in receiver, broad bandwidth, FIFO=64 bits
10 = JA in receiver, narrow bandwidth, FIFO=128 bits
11 = JA in transmitter, narrow bandwidth, FIFO=128 bits
