(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = Internal pulldown, IPU = Internal pullup. (To pull up a signal to the opposite supply rail, a 1-kΩ resistor should be used.)

I/O/Z
This pin is multiplexed between the USB clock generator, timer, and GPIO. For
the USB clock generator, it is clock output CLK_OUT1. This is configurable for 12
IPD
MHz or 24 MHz clock outputs.
For Timer0, it is the timer event capture input TIM_IN.
For GPIO, it is GPIO49.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = Internal pulldown, IPU = Internal pullup. (To pull up a signal to the opposite supply rail, a 1-kΩ resistor should be used.)
