Given the AVR Assembly program below written for the ATmega$328$PB microcontroller, fill in the program $($flash$)$ memory and data memory with appropriate values by hand. For instructions, list the instruction's mnemonic and replace labels, equates$/$definitions$,$ functions and operations in operands with their values in hexadecimal form. The first four instructions are entered to get you started. For values written to locations in data memory, list the $($potentially multiple$)$ values in hexadecimal form at the correct locations.

; define some constants

$.$ EQU STARTVAL $=3$

$.$ EQU ENDVAL $=14$

$.$ EQUSTEP$=4$

; ensure Stack Pointer holds last address in SRAM

LDI R$16,$ HIGH $($RAMEND$)$

OUT SPH$,$ R $16$

LDI R$16,$ LOW $($RAMEND$)$

OUT SPL$,$ R $16$

; load constants into GPRs for use

LDI R$16,$ STARTVAL

LDI R$17,$ STEP

LDI R$18,$ ENDVAL

PUSH R$16$ ; save R$16\text{'}$s value on stack

RCALL SUMVALS ; call subroutine

POP R$16$ ; restore R$16\text{'}$s value from stack

END: RJMP END ; infinite loop at program's end

; Subroutine repeatedly adds STEP $($R$17)$

; to STARTVAL $($R$16)$ until the sum becomes

; larger than ENDVAL $($R$18).$ Answer that is

; less than or equal to ENDVAL will be held

; in R$19.$

SUMVALS :

MOV R$19,$ R$16$ ; store current sum in R$19$

ADD R$16,$ R$17$ ; add STEP to sum in R$16$

CP R$18,$ R$16$; test if ENDVAL $>=$ sum

BRPL SUMVALS ; loop again if ENDVAL $$ sum

RET ; return from subroutine
