Note 1:
When the CPU bus is operated in the 8-bit mode (CMS = 1), the host should always write to the
lower byte (bits 0 to 7) first followed by the upper byte (bits 8 to 15).
Note 2:
The THDLC is a write-only register.
Note 3:
The Transmit FIFO can be filled to a maximum capacity of 256 bytes. When the Transmit FIFO
is full, it will not accept any additional data.
Bits 0 to 7/Transmit FIFO Data (D0 to D7).
Data for the Transmit FIFO can be written to these bits.
D0 is the LSB and is transmitted first while D7 is the MSB and is transmitted last.
Bit 8/Transmit Message End (TMEND).
This bit is used to delineate multiple messages in the Transmit
FIFO. It should be set to a one when the last byte of a packet is written to the Transmit FIFO. The setting
of this bit indicates to the HDLC controller that the message is complete and that it should calculate and
add in the CRC checksum and at least two flags. This bit should be set to zero for all other data written to
the FIFO. All HDLC messages must be at least 2 bytes in length.
