PT2 Known Button ROM Trace
This report follows the panel button edge path from the serial-visible reports back into the ROM input scanner.
The key table is the indirect handler table at H'2706, used by loc_1C0E after byte-level panel input changes are detected.

Practical Read
- CALL and CAM POWER do share the general panel edge path with many other buttons.
- The shared path is: panel byte snapshot -> shadow byte -> dirty bit ->
loc_1C0Ejump table -> handler ->loc_3E54report. - Other buttons diverge in their handlers: many require
F731/F730/F791session/menu gates, mutate page state, or emit different selectors. - Some table entries are
H'1C25, an immediateRTS, so those physical matrix positions are intentionally ignored in this firmware context.
