Bit #
Name
Default
Bit 0/Transmit Alternate Ones and Zeros (TAOZ). Transmit a …101010… pattern (customer disconnect
indication signal) at TTIP and TRING. The transmission of this data pattern is always timed off of TCLK.
Bit 1/Transmit Synchronization G.703 Clock Enable (TSCLKE)
Bit 2/Receive Synchronization G.703 Clock Enable (RSCLKE)
Bits 3 to 4/Monitor Mode (MM0 to MM1)
Bit 5/Receive-Clock Edge Select (RCES). Selects which RCLKO edge to update RPOSO and RNEGO.
Bit 6/Transmit-Clock Edge Select (TCES). Selects which TCLKI edge to sample TPOSI and TNEGI.
Bit 7/Unused, must be set to 0 for proper operation

0 = disable 1.544MHz (T1)/2.048MHz (E1) transmit synchronization clock
1 = enable 1.544MHz (T1)/2.048MHz (E1) transmit synchronization clock
0 = disable 1.544MHz (T1)/2.048MHz (E1) synchronization receive mode
1 = enable 1.544MHz (T1)/2.048MHz (E1) synchronization receive mode
0 = update RPOSO and RNEGO on rising edge of RCLKO
1 = update RPOSO and RNEGO on falling edge of RCLKO
0 = sample TPOSI and TNEGI on falling edge of TCLKI
1 = sample TPOSI and TNEGI on rising edge of TCLKI
