Function:
Description:
Logical AND for bit operands
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.
