Registers

ACCU1 to ACCU4 (32 Bits)
The accumulators are registers for processing bytes, words or double words. The address identifiers are loaded into the accumulators,
where they are logically gated. The result of the logic operation (RLO) is in ACCU1 and can be transferred from there to a memory cell.
The accumulators are 32 bits long.
Accumulator designations :
