3.3 CPU Registers
This section describes the CPU registers.
3.3.1 Accumulators A and B
Accumulators A and B are general-purpose 8-bit accumulators that contain operands and results of
arithmetic calculations or data manipulations.
3.3.2 Accumulator D
Accumulator D is the concatenation of accumulators A and B. Some instructions treat the combination of
these two 8-bit accumulators as a 16-bit double accumulator.
