Default
Bit 0/Function of the RLOS/LOTC Output (RLOSF)
Bit 1/Transmit Clock Source Select Bit 0 (TCSS0)
Bit 2/Transmit Clock Source Select Bit 0 (TCSS1)
Bit 3/Disable Idle Code Auto Increment (DICAI). Selects/deselects the auto-increment feature for the transmit
and receive idle code array address register. See Section 16.
Bit 4/Output Data Mode (ODM)
Bit 5/Signaling Integration Enable (SIE)
Bit 6/CRC-4 Recalculate (CRC4R)
Bit 7/MCLK Source (MCLKS). Selects the source of MCLK

COMMON CONTROL AND STATUS REGISTERS
0 = receive loss of sync (RLOS)
1 = loss-of-transmit clock (LOTC)
0 = addresses in IAAR register automatically increment on every read/write operation to the PCICR
register
1 = addresses in IAAR register do not automatically increment
0 = pulses at TPOSO and TNEGO are one full TCLKO period wide
1 = pulses at TPOSO and TNEGO are one-half TCLKO period wide
0 = signaling changes of state reported on any change in selected channels
1 = signaling must be stable for three multiframes in order for a change of state to be reported
0 = transmit CRC-4 generation and insertion operates in normal mode
1 = transmit CRC-4 generation operates according to G.706 intermediate path recalculation method
0 = MCLK is source from the MCLK pin
1 = MCLK is source from the TSYSCLK pin

The TCLK pin is always the source of transmit clock.
Switch to the clock present at RCLK when the signal at the TCLK pin
fails to transition after 1 channel time.
Use the scaled signal present at MCLK as the transmit clock. The
TCLK pin is ignored.
Use the signal present at RCLK as the transmit clock. The TCLK pin is
ignored.
