MPC5777c, eTPU:  input pins configuration

Hi,

 

On MPC5777  we configures eTPU B channel 0-1 as inputs (PCR147 -148) with PA = Primary function and IBE set to 1.

 

SIU PCR 147 Configuration Register:

 

Despite state changes on eTPU inputs pins, we still see 0 inside CSCR.IPS. Like there was no activity on the pins.

 

eTPU B CSCR Register:

 

We are able to play on the output pins. Our ETPU source code is running perfectly on MPC5644A.

 

ETPU B Configuration Register:

 

ETPU B Time Base Configuration Register:

 

Do you have any suggestions about maybe a missing SIU/ETPU configuration ?

 

 

Best Regards,

 

Cedric
