Question

Analyze the following code, and determine which mathematical operation is taking place. Note that you may need to look up rol and lsl operations. You may use AVR references to do this. The correct answer must be written in ONE WORD as a response.

;Numbers in R1:R0 and R3
ldi R16, 0x03; 0x0325 to R1:R0
mov R1,R16
ldi R16,0x25
mov R0,R16
clr R2;R2 is needed to shift the number to left,zero at start
ldi R16, 0x7A to R3
mov R3,R16
;clr result in R6:R5:R4
clr R6
clr R5
clr R4
