DESCRIPTION
Timer 2 and Timer 1
No external pins. The Timer 2 and Timer 1 peripheral pins are not pinned out as external pins.
Timer 0
CLK_OUT1/
TIM_IN/
GPIO49
E19 I/O/Z
DV_DD18
This pin is multiplexed between the USB clock generator, timer, and GPIO.
For Timer0, it is the timer event capture input TIM_IN.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) Specifies the operating I/O supply voltage for each signal
