Logic Inverted Input

user4957458

Hi All

There is some way to invert an GPIO input of the TMS28069, Is it logic (hardware) inside the TMS to do that? If so how to configure it? I have some hardware that inverts a bit and I want to invert back by the TMS hardware

I know that can be done by software but I am porting a solution in which the Microcontroller had that logic (in some pins)

Thanks

Hi Luis, If you are using the GPIO pin as external interrupt then you can change the polarity by configuring the POLARITY bit in XINTxCR register but if you are just reading the bit value from data register then this device does not have logic in hardware to invert the input.
