Discrete Input/Output (DIO)
The DIO function (Bank 0 and Bank 1) allows a TPU3 channel to be used as a digital I/O pin.
When a pin is used as a discrete input, a parameter indicates the current input level and the previous 15
levels of a pin. Bit 15, the most significant bit of the parameter, indicates the most recent state. Bit 14
indicates the next most recent state, and so on. The programmer can update the parameter when a transition
occurs, when the RCPU makes a request, or when a rate specified in another parameter is matched.
When a pin is used as a discrete output, it is set high or low only upon request by the RCPU. See Freescale
