Table 7: GPIO [44:32] on EB 200 as Alternative Function
Signal description: I: Input O: Output B: Bidirectional P: Power supply
Up: Internal pull-up Dn: Internal pull-down (I): Status during reset
_N at end of signal name means: Signal is Low active Example: LBU_IRQ0_N
Example of IO Function: B/O/O/I/ (I)  Function 1 = Bidirectional, Function 2 = Output, Function 3 = Output, Function 4 =
Input, (I) = IO Function during RESET = Input
Note: The GPIO[44:32] are only available as Inputs on EB200, if alternative function 2 or 3 is selected.
