Figure 8 Registers and Flags
Accumulator (A) and B Register (B)
A and B are 4-bit registers, and are used to hold the results of ALU(arithmetic and logical unit) operations
and to transfer data between memory, I/O ports, and other registers.
W Register (W), X Register (X), Y Register (Y)
W is a 2-bit register and X and Y are 4-bit registers. These registers are used in RAM register indirect
addressing. The Y register is also used in D port addressing.
