ANL
C, <src-bit>
Function:
Logical AND for bit variables
Description:
If the Boolean value of the source bit is a logic 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 affected . No other flags are
affected.
Only direct bit 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:
