This document is the HDL guide for the CONV-TTL-RS485 project~\cite{conv-ttl-rs485-ohwr}.
The HDL for the CONV-TTL-RS485 board uses the converter board common gateware~\cite{conv-common-gw}
as a subproject and adds some external logic to it to adapt for peculiarities on the CONV-TTL-RS485.
This short HDL guide explains these peculiarities and the corresponding logic implemented, and lists
This document explains these peculiarities and the corresponding logic implemented, and lists
the memory map for the gateware in Appendix~\ref{app:memmap}.
