12.3.1 Accumulator and Memory Instructions
Most of these instructions use two operands. One operand is either an accumulator or an index
register while the second operand is usually obtained from memory using one of the addressing
modes discussed earlier. These accumulator memory instructions can be divided into six subgroups:
These instructions are discussed in the following tables and paragraphs.
12.3.1.1
Almost all MCU activities involve moving data from memories or peripherals into the CPU or moving
results from the CPU to memory or to I/O devices. The load, store, and transfer instructions
associated with the accumulators are summarized in the following table. There are additional load,
store, push, and pull instructions associated with the index registers and stack pointer register
(see 12.3.2 Stack And Index Register Instructions).
