TMS320C55xx uart disable

I like to disable the internal uart on the TMS320C5545 from using the respected IO pins for Rx and Tx

Instead I like to configure both of them to be GPIO output pins with pulldown resistor enabled.

I tried the same procedure as I do on other GPIO pin, but have not been successful.

What is the correct procedure to disable the UART from using the io pins?

UART pin mux'ing is configurated via PPMODE bits of EBSR. As shown in data manual table 4-7, MODE 2 configures those pins to be GPIOs. The IPD resistors are enabled via the PDINHBR3 register, bit 12-15.

Hi Matt
Since this part is not announced in broad market and available under NDA, please route queries for this device to your local field/sales team.
Hopefully though Steve's answer helps close it.
