Could someone explain the codes clearly for me, please. This is assembly language which is very new for me. I'm trying to program an ARM controller using assembly language but it's not working.

1. text 2. global main 4@define constants, these can be used as symbols in your code 5.equ LED_CTL, Ox41210000 6. set SW_DATA, Ox41220000 8 @the set and equ directives are equivalent and can be used interchangeably _main: 1 ldr r1,-SW_DATA @load switch address from constant ldr r2,-LED_CTL @load LED address from constant 3 loop: ldr ro,[rl] @load switch value *r1 ->ro str ro,[r2] @store value to led register *r2
