Note:
Each GPIO line can be assigned to one of 4 peripheral functions; A, B, C or D (D is only avail-
able for UC3Bx512 parts). The following table define how the I/O lines on the peripherals A, B,C
or D are multiplexed by the GPIO.

The exposed pad is not connected to anything internally, but should be soldered to ground to
increase board level reliability.
