Answer:
see explaination
Explanation:
1.) Each time the main program execution starts at address 0000 - Reset Vector. The address 0004 is “reserved” for the “interrupt service routine” (ISR).
ORG 0x000 ; processor reset vector
goto main ; go to beginning of main program
ORG 0x004 ; interrupt vector location
movwf w_temp ; save off current W register contents
movf STATUS,w ; move status register into W register
movwf status_temp ; save off contents of STATUS register
.

main
3.) Push button switch is connected to the first bit of PORT B (RB0) which is configured as an input pin. When the switch is pressed this pin RB0 will be grounded. The LED is connected to the first bit of PORT B (RA0)
4.) Push button switch is connected to the first bit of PORT B (RB0) which is configured as an input pin. When the switch is pressed this pin RB0 will be grounded. The LED is connected to the first bit of PORT B (RA0)
5.) Push button switch is connected to the first bit of PORT B (RB0) which is configured as an input pin. When the switch is pressed this pin RB0 will be grounded. The LED is connected to the first bit of PORT B (RA0)
