Accumulator register
16-bit immediate constant value
Shift value (default is "<< #0" if no value specified)
Perform a bitwise AND operation on the ACC register with the given 16-bit
unsigned constant value left shifted as specified. The value is zero extended
and lower order bits are zero filled before the AND operation. The result is
stored in the ACC register:
ACC = ACC AND (0:16bit << shift value);
The load to ACC is tested for a negative condition. If bit 31 of ACC is 1, then the
negative flag bit is set; otherwise it is cleared.
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 instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
