Low power mode HCS12

[bastbare]

Hey, I'm student and i'm working with the MC9S12DP512. My project is to put the µC into the different modes of consumption.

My μC is mounted on a board with only 2 buttons on PT7 & PT6 (vector address FFE0 / FFE2). Is it possible to wake up the μC with one of these interruptions? Currently, it consumes 50mA and I'd like to pass below 15mA.

I read the application note with the instructions to use : asm ANDCC #0x7F; / asm WAI or STOP ... 

So, do you have some example ?

Thanks

Hi, 

I didn't read this application note. I understand my problem now. I'll come back if necessary when i'll have a new card with the good mapping for the low power modes.

Thanks a lot :smileywink:

Hi,

Unfortunately, port interrupts are available only on port P, H and J.  See Table 3-2. In S12DP256PIMV3.
