1. Write a program that add 0x13 for 100 times by itself and store it in 0x30 and 0x31 of the file register:

2. Write a program that search through the following 20 hex numbers and store the smallest number at address 0x30 and largest number at address 0x31 and compute the Range (max min) and store the result in the address 0x40.

0x20,0x34,0xa2,0x4b,0xc2

0x12,0xc2,0xb2,0x9b,0xe2

0x29,0x90,0x02,0x8b,0xca

0xF2,0xb4,0x2c,0x9a,0x82

How many times the following loop will be executed calculate the delay for a 4 MHZ oscillator.

myreg equ 0x88

delay movlw 0x00 ; 1 instr cycle

movwf myreg ; 1 instr cycle

again nop ; 1 instr cycle

nop ; 1 instr cycle

nop ; 1 instr cycle

nop ; 1 instr cycle

decf myreg, f ; 1 instr cycle

bnz again ; 2 instr cycle

return ; 1 instr cycle

3. Write a code that makes the PORTB as output and PORTA as input. Check for the status of S2 (bit 4 on PORTA) if the switch is pressed turn on all of the LEDs attached to PORTBs with enough delay.

4. (Extra Credit) Write a piece of code that counts from zer0 to 99 using four digit 7 segments.
