Only answer questions 1 and 2. I will rate

LAB 1 a) Test the operation of an up-counter on your AVR trainer. Use wires to connect the LEDs to each pin of the port D and perform the following steps: b) Assemble the following code: LDI OUT LDI OUT R20, HIGH (RAMEND) SPH, R20 R20, LOW (RAMEND) SPL, R20 LDI OUT ;make the port B an output port R20, OxFF DDRD, R20 LOOP: LDI OUT INC RCALL RJMP R20, 0 PORTD, R20 R20 DELAY LOOP igoto LOOP DELAY: DL1: DL2: DL3: LDI R21, 32 LDI R22, 200 LDI R23, 250 NOP NOP DEC R23 BRNE DL3 DEC R22 BRNE DL2 DEC R21 BRNE DL1 RET Questions: 1) In this Lab, we used BRNE (Branch Not Equal) instruction. Explain how it works. 2) Is this a valid instruction? BRNE R20, PINB, OVER LAB 1 a) Test the operation of an up-counter on your AVR trainer.
