IA6805E2
29 August 2007
Microprocessor Unit
As of Production Version 00
Instruction Set Description
The MPU has 61 basic instructions divided into 5 types. The 5 types are Register/memory, read-
modify-write, branch, bit manipulation, and control.
Register/Memory Instructions:
Most of the following instructions use two operands. One is either the accumulator or the
index register and the other is obtained from memory. The jump unconditional (JMP) and
jump to subroutine (JSR) instructions have no register operand.
Function
M nem onic
Load A from m em ory
LD A
Load X from m em ory
LD X
Store A in memory
STA
Store X in memory
STX
Add memory to A
AD D
Add memory and carry to A
ADC
Subtract m em ory
SUB
Subtract m em ory from A with Borrow
SBC
AND memory to A
AN D
OR memory with A
O RA
Exclusive O R m em ory with A
EO R
Arithm etic com pare A with m em ory
CM P
Arithmetic compare X with memory
CPX
Bit test m em ory with A (logical com pare)
BIT
Jum p U nconditional
JM P
Jum p to subroutine
JSR
Read-Modify-Write Instructions:
These instructions read a memory or register location, modify or test its contents and then
write the modified value back to memory or the register.
