## also look at stack_machine_cond_jump test
## we're going to write numbers from 0 to 639 at addresses h100000 to h1009FC
## and then write non-zero value at h100A00
# this will translate to 2 16-bit instructions
set_sp h100000
## load current value of timer, in a loop
## this is address 4 we later jump to
# this will translate to 2 16-bit instructions
loadwzx h1C0008
## loop until timer exceeds 500
# this will translate to 2 16-bit instructions
const 500
# this will translate to 1 16-bit instruction
lt
# this will translate to 1 16-bit instruction
cond_jump 4
## now, light led2
# this will translate to 1 16-bit instruction
const 1
# this will translate to 2 16-bit instructions
storew h1C0006
## second loop, analogous to the first one
## this is address 22 we later jump to
# this will translate to 2 16-bit instructions
loadwzx h1C0008
## loop until timer exceeds 1000
# this will translate to 2 16-bit instructions
const 1000
# this will translate to 1 16-bit instruction
lt
# this will translate to 1 16-bit instruction
cond_jump 22
## now, switch led2 off
# this will translate to 1 16-bit instruction
const 0
# this will translate to 2 16-bit instructions
storew h1C0006
## third loop, analogous to the first two
## this is address 40 we later jump to
loadwzx h1C0008
## loop until timer exceeds 1500
const 1500
lt
cond_jump 40
## finish operation (will also put led1 on)
halt
