Accumulator register
Addressing mode (see Chapter 5)
Perform a bitwise AND operation on the ACC register with the zero-extended
content of the location pointed to by the "loc16" address mode. The result is
stored in the ACC register:
ACC = ACC AND 0:[loc16];
Clear flag.
The load to ACC is tested for a zero condition. The zero flag bit is set if the
operation generates ACC = 0; otherwise it is cleared
This operation is repeatable. If the operation follows a RPT instruction,
then the AND instruction will be executed N+1 times. The state of the Z
and N flags will reflect the final result.
