INSTRUCTION SET
The MCU has a set of 62 basic instructions. They can be divided into ve different
types: register/memory, read-modify-write, branch, bit manipulation, and control.
The following paragraphs briey explain each type. For more information on the
instruction set, refer to the M6805 Family User’s Manual (M6805UM/AD2) or the
associated MC68HC05 Data Sheet.
9.1
REGISTER/MEMORY INSTRUCTIONS
Most of these instructions use two operands. One operand is either the accumula-
tor 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.
Function
Load A from Memory
Load X from Memory
Store A in Memory
Store X in Memory
Add Memory to A
Add Memory and Carry to A
Subtract Memory
Subtract Memory from A with Borrow
AND Memory to A
OR Memory with A
Exclusive OR Memory with A
Arithmetic Compare A with Memory
Arithmetic Compare X with Memory
Bit Test Memory with A (Logical Compare)
Jump Unconditional
Jump to Subroutine
