3 Instruction Functions

Chapter 1 Overview

The instruction set has been kept simple so that C compiler output is compact and highly optimized.

*1. MOVB, MOVH, and JSR are assembler shorthand for instruction sequences. RTS is an alias for RETS.

*2. The ASR Dn and LSR Dn variants are assembler shorthand for single-bit shifts of the specified register.

The BSET and BCLR instructions temporarily disable interrupts and lock the bus for exclusive

CPU use while they execute.

AM31

AM32

The BSET and BCLR instructions do not lock the bus for operations on

data in the cachable region of external memory.
