12.2 Introduction
The microcontroller unit (MCU) instruction set has 62 instructions and
uses eight addressing modes. The instructions include all those of the
M146805 CMOS (complementary metal oxide silicon) Family plus one
more: the unsigned multiply (MUL) instruction. The MUL instruction
allows unsigned multiplication of the contents of the accumulator (A) and
the index register (X). The high-order product is stored in the index
register, and the low-order product is stored in the accumulator.
12.3 Addressing Modes
The central processor unit (CPU) uses eight addressing modes for
flexibility in accessing data. The addressing modes provide eight
different ways for the CPU to find the data required to execute an
instruction. The eight addressing modes are:
Inherent
Immediate
Direct
Extended
Indexed, no offset
Indexed, 8-bit offset
Indexed, 16-bit offset
Relative
