TMS320F280049C: The twoGPIO boot pins how to configure for other peripheral functions?

Part Number: TMS320F280049C

Hi Experts,

I am asking this for my customer, and they want to know the twoGPIO boot pins how to configure for other peripheral functions?

Or the GPIO24 configure as the ePWM or PMBus, is there anything to attention?

Like the below mentioned, weak-pullups? How much the resistance? Thanks!

Shaoxing,
I've assigned your post to the subject matter expert, but due to US Holiday, please expect our response by the end of day Monday.

Shaoxing,

Since boot pins will be sensed at power up, customer will just to ensure that the GPIO driver(typ 4mA) can overdrive the PU/PD during functional use in their system. I think 10kOhm PU/PD for boot will be a good value, only consuming 330uA when overdriven by the device.

Best,

Matthew
