SYSTEM CONFIGURATION A Register and X Register The A register (or accumulator : ACC) is a 4-bit general purpose register. The register is mainly used in conjunction with the ALU, C flag and RAM to transfer numerical value and data to perform various operations. The A register is also used to transfer data between input and output pins. The X register (or auxiliary accumulator) is a 4-bit register and can be used as a temporary register. It loads contents of the A register or its content is transferred to the A register. When the table reference instruction PAT is used, the X and A registers load ROM data. A pair of A and X registers can accommodate 8-bit data. Arithmetic and Logic Unit (ALU) and Carry Signal Cy The ALU performs 4-bit parallel operation The ALU operates binary addition in conjunction with RAM, C flag and A register. The carry signal Cy is generated if a carry occurs during ALU operation. Some instructions use Cy : ADC instruction sets/clears the content of the C flag; ADX instruction causes the program to skip the next instruction. Note that Cy is the symbol for carry signal and not for C flag. 3 3 0 0 A register X register EXAX instruction Fig. 1 Data Transfer Example between A Register and X Register c Areg ALU Result of operation 4-bit data 4-bit data Fig. 2 ALU |
