Accumulator – ACC

The Accumulator is central to the operation of any microcontroller and is closely related with

operations carried out by the ALU. The Accumulator is the place where all intermediate results from

the ALU are stored. Without the Accumulator it would be necessary to write the result of each

calculation or logical operation such as addition, subtraction, shift, etc., to the Data Memory

resulting in higher programming and timing overheads. Data transfer operations usually involve the

temporary storage function of the Accumulator; for example, when transferring data between one

user defined register and another, it is necessary to do this by passing the data through the

Accumulator as no direct transfer between two registers is permitted.

Program Counter Low Register – PCL

To provide additional program control functions, the low byte of the Program Counter is made

accessible to programmers by locating it within the Special Purpose area of the Data Memory. By

manipulating this register, direct jumps to other program locations are easily implemented. Loading

a value directly into this PCL register will cause a jump to the specified Program Memory location,

however, as the register is only 8-bit wide, only jumps within the current Program Memory page are

permitted. When such operations are used, note that a dummy cycle will be inserted.
