ANL CY,<src-bit>
Function:
Logical–AND for bit variables
Description:
If the boolean value of the source bit is a logical 0, clear the CY flag; otherwise leave the CY flag in its current state.
A slash (”/”) preceding the operand in the assembly language indicates that the logical complement of the addressed
bit is used as the source value, but the source bit itself is not affected.
Only direct addressing is allowed for the source operand.
Example :
Set the CY flag if, and only if, P1.0 = 1, ACC. 7 = 1 and OV = 0:
ANL CY,bit51
[Encoding]
ANL CY,/bit51
[Encoding]
FLAGS :
Hex Code in:
Binary Mode = [Encoding]
Source Mode = [Encoding]
Hex Code in:
Binary Mode = [Encoding]
Source Mode = [Encoding]
MOV CY,P1.0 ; Load carry with input pin state
ANL CY,ACC.7 ; AND carry with accumulator bit 7
ANL CY,/OV ; AND with inverse of overflow flag
