Other Parts Discussed in Thread: TCAN4550

Hi Team,

There is a good new that DIN TCAN4550 ! Currently the customer has a request,

Regarding this project , the physical line was transferred to can ECU, need to add UART

Customer want to change the current nWKRQ pin of p4.2 to a complete set of UART (P4.2&P4.3)
And looked at the TCAN4550 WKRQ in the picture below, customer want to confirm that other GPIO pins can be exchanged ?

(msp430 has two sets of UART ,one set has been used up (burning use))
