Hey,
I found following docs for:

• M16C_60 & M16C_20 & M16C_Tiny (Software Manual):
  https://www.renesas.com/en/document/mah/m16c60-m16c20-m16ctiny-series-software-manual

• M16C_60 & M16C/20 (Application Note):
  https://www.renesas.com/ja/document/apn/programming-guidelines-assembly-language-rej05b0085-0102

• M16C_80 (Software Manual):
  https://www.renesas.com/en/document/mas/m16c80-series-software-manual
  https://datasheet.octopart.com/M30805FGGP%23U5-Renesas-datasheet-82748.pdf

it looks like there are some stuff in archive.org such as, but archive.org says it's offline for the moment :(.
I'm dropping this stuff here, cuz I believe some stuff should be checked, such as doc versions and etc.

and btw, Tnx for this great repo!
