This document is intended to document certain inner workings of the CPU.

There have been efforts by emu-russia and gekkio to have the CPU decapped, and so we have the decode ROM accessible to us. This means, that we know exactly what each opcode does (besides some nuanced behavior related to HALT, STOP, and some state management related to interrupts and power saving which are hard to untangle).
