XRL A, @R0H

XRL A, @R0L

<1> Instruction code:

1 010 0/1 1000 0

<2> Cycle count:

<3> Function:

(A)

← (A) ∨ (P13), (R0))7-4 (in the case of XRL A, @R0H)

← A3 • ROM7

(A)

← (A) ∨ (P13), (R0))3-0 (in the case of XRL A, @R0L)

← A3 • ROM3

The accumulator contents and the program memory contents specified by the control register P13 and

If H is specified, b7, b6, b5, and b4 take effect. If L is specified, b3, b2, b1, and b0 take effect.

XRL A, #data4

<1> Instruction code:

1 01011000 1

0 00000 d3 d2 d1 d0

<2> Cycle count:

<3> Function:

(A)

← (A) ∨ data4

← A3 • data43

The accumulator contents and the immediate data are exclusive-ORed and the results are entered in

the accumulator.

INC A

<1> Instruction code:

1 01001001 1

<2> Cycle count:

<3> Function:

(A)

← (A) + 1

A = 0

← 1

else

← 0

The accumulator contents are incremented (+1).

RL A

<1> Instruction code:

1 11001001 1

<2> Cycle count:

<3> Function:

(An + 1)

← (An), (A0) ← (A3)

← A3

The accumulator contents are rotated anticlockwise bit by bit.

RLZ A

<1> Instruction code:

1 11101001 1

<2> Cycle count:

<3> Function:

A = 0

reset

else

(An + 1)

← (An), (A0) ←(A3)

← A3

The accumulator contents are rotated anticlockwise bit by bit.

If A = 0H at the time of command execution, an internal reset takes effect.
