Description:
Perform a 16-bit logical AND operation, bit for bit, on
the contents of the A-register and the contents of the X-
register. Store the 16-bit result back into the A-register.
The previous contents of the A-register are overwritten
and lost.
Register X can be any of the 16 CPU registers.
PC is incremented once to point to the next instruction
in program memory.
Two’s-complement data format is not preserved.
No branching occurs.
No other registers are affected.

Description:
Perform a 16-bit logical OR operation, bit for bit, on the
contents of the A-register and the contents of the X-reg-
ister. Store the 16-bit result back into the A-register.
The previous contents of the A-register are overwritten
and lost.
Register X can be any of the 16 CPU registers.
PC is incremented once to point to the next instruction
in program memory.
Two’s-complement data format is not preserved.
No branching occurs.
No other registers are affected.
ADX
Op-code:
Operation:
CPU Cycles required:
Description:
Perform a 16-bit arithmetic addition of the A-register
and the contents of the X-register. Store the low 16 bits
of the result back into the A-register. Any overflow bit
resulting from the addition operation is lost. The previ-
A-register ← A-register OR X-register
PC-register ← PC + 1 (point to next instruction)

A-register ← A-register + X-register
PC-register ← PC + 1 (point to next instruction)

STX
Op-code:
Operation:
CPU Cycles required:
Description:
Perform a 16-bit move operation from the A-register into
the X-register. The A-register contents are unchanged.
The previous contents of the X-register are overwritten
and lost.
Register X can be any of the 16 CPU registers.
PC is incremented once to point to the next instruction
in program memory.
Two’s-complement data format is preserved.
No branching occurs.
No other registers are affected.
