Tx Synchronous fraction data interface
This bit selects whether TxCHCLK or TxSERCLK will be used for fractional
data input if fractional interface is enabled. If TxSERCLK is selected to clock in
fractional data input, TxCHCLK will be used as an enable signal
0 = Fractional data Is clocked into the chip using TxChCLK if fractional data
interface is enabled.
1 = Fractional data is clocked into the chip using TxSerClk. TxChClk is used
as fractional data enable.

:
The Time Slot Identifier Pins (TxChn[4:0]) still indicates the time slot
number if fractional data interface is not enabled. Fractional Interface
can be enabled by setting TxFr1544 to 1

0
Transmit payload clock enable/TxSYNC is Active Low
This exact function of this bit depends on whether the T1 framer is configured
to operate in base rate or high speed modes of operation.
If the T1 framer is configured to operate in base rate - TxPayload Clock:
This bit configures the framer to output a regular clock or a payload clock on
the transmit serial clock (TxSERCLK) pin when TxSERCLK is configured to be
an output.
0 = Configures the framer to output a 1.544MHz clock on the TxSERCLK pin
when TxSERCLK is configured as an output.
1 = Configures the framer to output a 1.544MHz clock on the TxSERCLK pin
when transmitting payload bits. There will be gaps on the TxSERCLK output
pin when transmitting overhead bits.
If the T1 framer is configured to operate in high-speed or multiplexed
modes - TxSYNC is Active Low:
This bit is used to select whether the transmit frame boundary (TxSYNC) is
active low or active high.
0 = Selects TxSync to be active “High”
1 = Selects TxSync to be active “Low”
