New reference pages covering the V2.4a reverse engineering:
- Overview with architecture diagram and memory layout
- Command dispatch: XOR pattern, two dispatchers, compound commands
- Memory map: RAM variables, EEPROM layout, SFR definitions
- I2C & synthesizer: RDA1846S communication, frequency programming
- Source files: links to annotated assembly, C port, Python tools
These document the 19,053-line annotated assembly and 12,020-line
readable C port produced by Phases 1-3 of the RE project.
Documents the 6-pin ICSP header for bootloader forcing (jumper
method) and direct PICkit programming. Includes pinout table,
PICkit connection mapping, MPLAB X/IPECMD instructions, and
notes on the PIC18F46J11 vs PIC18F45K22 discrepancy between
schematics and manual.
