FPGA 6502: Implement 'ROL abs' part 2 of 3

Показать описание
We finally start implementing an actual opcode. This is part 2 of 3, in which set the control lines (microcode) for perform the actual rotate and write the result to memory.

Project CompuSAR aims at building 70's and 80's computers on a low-end FPGA. Most of the project works from scratch, and this channel half documents the progress, half teaches about the concepts that come into play when designing such a system.
