Bits 8 to 11/Transmit Flag Generation Bits 0 to 3 (TFG0/TFG1/TFG2/TFG3). These four bits determine how
many flags and interfill bytes are sent between consecutive packets.
Bit 12/Transmit Zero Stuffing Disable (TZSD). When this bit is set low, the HDLC engine performs zero
stuffing on the outgoing data stream. When this bit is set high, the outgoing data stream is not zero stuffed. This
bit is ignored when the HDLC engine is configured in the transparent mode (TTRANS = 1).
