Hi.

I'm using CYT2B9.

 

I'm trying to use CAN0_0_TX and CAN0_0_RX pins.

And I confirmed that P2.0(CAN0_0_TX), P2.1(CAN0_0_RX) / P8.0(CAN0_0_TX), P8.1(CAN0_0_RX) are available.

The Power Source of P2.0/P2.1 is VDDD, and the Power Source of P8.0/P8.1 is VDDIO_1.

 

Q: Are there any differences in CAN operation depending on I/O Port Power Source?
(ex. noise  related)

 

Thanks & Best regards

Hi @taegyunahn,

The differences in CAN operation depending on I/O Port Power Source is only in the eFuse Programming state (not noise-related thing). As explained in the image below (from CYT2B9 Datasheet, Pg 93).
