While it's 32 bits, copying around 32-bit values with the CPU is mostly avoided. There are 256 32-bit registers (TBD- RAM or FPGA registers. Former allows swapping in new sets) and one 32-bit accumulator. Any of these can hold useful constants (including 0, 1, etc) for reference. It's similar to the 6502 accumulator and zeropage values. Commands are issued by writin..." Tag: Visual edit
