in program memory.
Two’s complement data format is preserved.
No branching occurs.
No other registers are affected.
ANX
AND Register X with Register A
Op-code:
0010 XXXX_BINARY 2Xh
Operation:
A-register ← A-register AND X-register
PC-register ← PC + 1 (point to next instruction)
CPU Cycles required:
1 cycle
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 A-register. The
previous contents of 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.
ORX
OR Register X with Register A
Op-code:
0011 XXXX_BINARY 3Xh
Operation:
A-register ← A-register OR X-register
PC-register ← PC + 1 (point to next instruction)
CPU Cycles required:
1 cycle
Description:
Perform a 16-bit logical OR operation, bit for bit, on the
contents of the A-register and the contents of X-regis-
ter. Store the 16-bit result back into A-register. The pre-
vious contents of 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
ADD Register X to Register A
Op-code:
0100 XXXX_BINARY 4Xh
Operation:
A-register ← A-register + X-register
PC-register ← PC + 1 (point to next instruction)
CPU Cycles required:
1 cycle
Description:
Perform a 16-bit arithmetic addition of the A-register
and the contents of X-register. Store the low 16 bits of
the result back into A-register. Any overflow bit result-
ing from the addition operation is lost.
The previous contents of 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 preserved.
No branching occurs.
No other registers are affected.
STX
Store Register X
Op-code:
0101 XXXX_BINARY 5Xh
Operation:
X-register ← A-register
PC-register ← PC + 1 (point to next instruction)
CPU Cycles required:
1 cycle
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 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.
