Bit #
Name
Default
Bit 0: DS3 Mode Select (DS3M). Selects DS3 or E3 operation. It must be set immediately after reset to select DS3
mode.
Bit 1: C-Bit Parity Mode Enable (CBEN). This bit is only active when the framer is in DS3 mode. When this bit is
logic 0, C-Bit Parity is defeated and the C bits are sourced from the TDAT input pin.
Bit 2: DS3/E3 Transmit Pass-Through Enable (TPT). When this bit is set to logic 1, the transmit formatter
sources data from the TDAT input on every TCLK cycle and does not insert framing overhead into the transmit data
stream. In this mode the TDEN/TGCLK output still marks where the payload bits would be if TPT were not enabled,
and the TSOF output still marks the start of a frame. When in this mode, the BERT does not function in payload-
only mode; entire-frame mode should be used instead.

0 = E3 mode
1 = DS3 mode
0 = disable C-Bit Parity mode (also known as the M23 mode)
1 = enable C-Bit Parity mode
0 = configure the formatter to insert framing overhead bits
1 = configure the formatter to pass through TDAT data without inserting framing overhead bits
