Hi I dont see anything mentioned in the C5416 datasheet about the TOUT (timer out) pin being able to be used as a GPIO pin. Is it still possible to configure this pin as GPIO just as it is in some of the other DSPs of the C54x series? Also, i was wondering if there a

Hi all, I have configured the McBSP #1 as GPIO (RRST_ = 0 RIOEN = 1). When I read the voltage on that pin (the pin is not connected, working with 5509 EVM from Spectrum Digital), I read 0 but the DSP read a logical 1 If I link the pin to the ground, the DSP sees a 0.
