9.4 Accumulator Manipulation Instructions

ANL A, R0n

ANL A, R1n

<1> Instruction code:

1 101 R4 0R3 R2 R1 R0

<2> Cycle count:

<3> Function:

(A)

← (A) (Rmn) m = 0, 1 n = 0 to F

← A3 • Rmn3

The accumulator contents and the register Rmn contents are ANDed and the results are entered in the

accumulator.

ANL A, @R0H

ANL A, @R0L

<1> Instruction code:

1 101 0/1 1000 0

<2> Cycle count:

<3> Function:

(A)

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

← A3 • ROM7

(A)

← (A) ((P13), (R0))3-0 (in the case of ANL 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.

• Program memory (ROM) organization

1 10111000 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 ANDed and the results are entered in the

accumulator.
