1.1  Communication Protocol
The AGB dedicated protocol utilizes an RZ modulation method.
Time is divided into fixed intervals, and the presence or absence of optical input during those intervals distinguishes signals.

A general schematic is shown below:

The 1bit signal width changes depending on the data communication speed.
1bit signal width (µ sec) = 1000 ÷ data transfer rate (kbps).



1.2  Communication Speed
The data communication speed varies widely, depending on the ROM /RAM operating versions.
Additionally, when using this version operation in ROM, the communication speed varies depending on the ROM access wait cycles.

ROM version:  Approximately (or up to) ~ 47kbps
CPU internal RAM version:   Approximately 104.2kbps
