I hope you understand what the code is doing.


Edit: There is a mistake in flowchart. I will upload the new one.

PHP: 
;initialization of regiaters

Immidiate value 0x01 is loaded into register R2
Immidiate value 0xF0 is loaded into register R3

;main code starts from here

register R0 is loaded with 0x81

registers R2 is ANDed with R2 and result stored in R2	; 0x01 AND 0x01 = 0x01

If result of previous operation was 0 then jump to label xyz else continue

;continue code

	load register R0 with 0x82
	registers R0 and R3 are ANDed and result stored in R0
	unconditional jump to label wzp


;xyz code

		load register R0 with 0x82
		register R0 and R3 are ORed and result stored in R0
;wzp code	contents of register R0 is stored at address 0x82
		unconditional jump to start of main code
