Operation
This capability supports custom interfacing requirements, such as the ability to communicate
with LEDs, digital buttons, and other devices that are not directly supported by any of the
i.MX28 specialized hardware interfaces.
Each pin is connected to one, two, or three specialized hardware interfaces, in addition to
the GPIO function available on banks 0 through 4. The description of each pin in and
contains full details of which specialized hardware interfaces are attached to that pin. For
example, the package pin named PWM0 is shared between the PWM and debug UART
hardware interfaces.
Users define which of the available hardware interfaces controls each pin by writing a
two-bit field for that pin into one of the HW_PINCTRL_MUXSELx registers.
Table
Both 289 and 204 packages have same mux options, but some pins on 289 package are not
available on 204 package and caused those related mux unavailable too. These unavailable
pins for 204-pins package are marked gray on muxreg row in .
