CAN TX pin during start at HIGH during GIO usage

Constantin Wiesener

Hi,

we are using the CAN TX of CANREG3 as a GIO out. And before the debugger reaches the caninit() the pin is always high although it is configured with pull down and initial output low. After the initialization the pin works correct.

We are using the Hercules development board and we need the pin to be always low during start up since we are switching a high voltage capacitor as a load pump.

Any suggestions?


Kind regards,

C.W.
