USART2 setting for 1MHzCPU + 4PLL

[longpole001]

i am slowly redesigning the unit to use less power
one of the main problems i have is that the unit was intended to receive rf when it was not transmitting , not to sleep
but button cells wont last that long when doing that

any way another question has come to light which i am not clear on the answer


i have routine that sets the sleep command
i have a interupt triggered routine to goto when it it wakes up ,
but where does the rotuine return to when its completed

it does not seem to return to the place after the sleep command ??

Pseudocode:

mainloop:
  Sleep                        ; go to sleep
  on interrupt do something    ; wake-up and jump to your ISR
  goto mainloop:               ; return here
