Bit 8/Transmit Invert Data (TID).
The control bit determines whether all of the data from the HDLC
controller (including flags and CRC checksum) are inverted after processing.
0 = do not invert data (normal operation)
1 = invert all data
Bit 9/Receive Invert Data (RID).
The control bit determines whether all of the data into the HDLC
controller (including flags and CRC checksum) are inverted before processing.
0 = do not invert data (normal operation)
1 = invert all data
Bits 10 to 12/Transmit Low Watermark Select Bits (TLWMS0 to TLWMS2).
These control bits
determine when the HDLC controller should set the TLWM status bit in the HDLC status register (HSR).
The TLWM status bit is set to a 1 when the transmit FIFO contains less than the number of bytes
configured by these bits.

Bits 13 to 15/Receive High Watermark Select Bits (RHWMS0 to RHWMS2).
These control bits
determine when the HDLC controller should set the RHWM status bit in the HDLC status register (HSR).
The RHWM status bit is set to a 1 when the receive FIFO contains more than the number of bytes
configured by these bits.
