C , <src-bit>

Function:

Logical-AND for bit variables

Description:

If the Boolean value of the source bit is a logical 0 then clear the carry flag; otherwise

leave the carry 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 affceted. No other flsgs are affected.

Only direct addressing is allowed for the source operand.

Example:

Set the carry flag if, and only if, P1.0 = 1, ACC. 7 = 1, and OV = 0:

MOV C, P1.0

;LOAD CARRY WITH INPUT PIN STATE

ANL C, ACC.7

;AND CARRY WITH ACCUM. BIT.7

ANL C, /OV

;AND WITH INVERSE OF OVERFLOW FLAG
