TQFP48 / QFN48 Pinout Note: On QFN packages, the exposed pad is not connected to anything. 4.2 Peripheral Multiplexing on I/O lines 4.2.1 Multiplexed signals 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.
