Magnus:

I suspect what you want to do is the following:

Tempo EQU 20h
AA EQU Tempo.0
BB EQU Tempo.1
...etc...

Your current code is referencing IRAM address 32h. That IRAM is not bit-addressable. Only IRAM addresses 20h through 2Fh are bit-addressable. Alternatively, you could do the assign:

Tempo EQU 32

(without the trailing "h"). 32 decimal is the same as 20h, so by just getting rid of the hex suffix on your equates will also solve your problem.
