Pin Function Descriptions 11
Symbol
Pin(s)
Type Description
CLK16N
CLK16P
GND
39 A Crystal oscillator input/output (RF reference oscillator)
40 A Crystal oscillator input/output (RF reference oscillator)
Center pad
P Ground on center pad of QFN, must be connected
A = analog signal
I = digital input signal
O = digital output signal
I/O = digital input/output signal
N = not to be connected
P = power or ground
All digital inputs are Schmitt trigger inputs, digital input and output levels are LVCMOS/LVTTL
compatible. Port A Pins (PA0—PA7) must not be driven above VDD_IO, all other digital inputs are
5V tolerant.
3.1. Alternate Pin Functions
GPIO Pins are shared with dedicated Input/Output signals of on-chip peripherals. The following
table lists the available functions on each GPIO pin.
