5.2
8-Bit Accumulator (A)
The accumulator is the general-purpose register for the microcontroller.
5.3
8-Bit Temporary Register (X)
The “X” register is available to the firmware for temporary storage of intermediate results. The microcontroller can perform indexed
operations based on the value in X. Refer to Section 5.6.3 for additional information.
