SECTION 16
INSTRUCTION SET
The MCU has a set of 62 basic instructions. They can be divided into five different types:
register/memory, read-modify-write, branch, bit manipulation, and control. The following
paragraphs briefly explain each type. For more information on the instruction set, refer to
the
M6805 Family User’s Manual (M6805UM/AD3) or the associated MC68HC05 Data
Sheet.
16.1
REGISTER/MEMORY INSTRUCTIONS
Most of these instructions use two operands. One operand is either the accumulator or the
index register. The other operand is obtained from memory using one of the addressing
modes. The jump unconditional (JMP) and jump to subroutine (JSR) instructions have no
register operand. Refer to the following instruction list.
16.2
READ-MODIFY-WRITE INSTRUCTIONS
These instructions read a memory location or a register, modify or test its contents, and
write the modified value back to memory or to the register. The test for negative or zero
(TST) instruction is an exception to the read-modify-write sequence since it does not modify
the value. Do not use these read-modify-write instructions on write-only locations. Refer to
the following list of instructions.
