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.

ORX

OR Register X with Register A

Op-code:

0011 XXXXBINARY 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 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

ADD Register X to Register A

Op-code:

0100 XXXXBINARY 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 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-

ous 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 preserved.

No branching occurs.

No other registers are affected.

STX

Store Register X

Op-code:

0101 XXXXBINARY 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 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.

SLX

Shift Left Register X

Op-code:

0110 XXXXBINARY 6Xh
