Question

In the following example I want to see if bit 1 in register r24 is set. Consequently, I would set bit 1 in my "test" byte (register r16) to 1. The answer is no so the contents of output register r24 is zero. r16 00000010 r24 = 00000000 r24 = 00100001 5. Write the single logical instruction below, with inputs r16 and r24, and output r24. Where mnemonics r16 and r24 are two of the AVR's 32 8-bit general purpose registers. Assume r24 initially contains the byte you want to test, and register r16 contains the test sequence in our example 000000102)

Explanation / Answer

XNOR r24 r16

If the test pattern is matched then ohtput result's one, otherwisd zero will be stored in r24.
