PWM Output as General Purpose Output

Question asked by herb70 on Sep 16, 2011

I am using a Blackfin BF532 in a product and need to generate a PRBS pattern for a noise signal. The only pin I have available is TMR0. Is it possible to use the TMR0 pin in PWM_OUT mode in a way similar to a GPIO pin to generate the PRBS pattern. It looks like you can output a HI level for binary 1 (100% duty cycle), but not a LO for binary 0 (0% duty cycle). Any ideas would be gratefully received.
