Technical Data
10.2 Introduction
The microcontroller unit (MCU) instruction set has 62 instructions and
uses eight addressing modes. The instructions include all those of the
M146805 complementary metal oxide semiconductor (CMOS) 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.
10.3 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
Relative
