Pin for optional external synthesizer loop filter; leave unconnected if not used
It is recommended to use the internal loop filter
Not to be connected
Ground
Optional reset input. If not used this pin must be connected to VDD.
Default functionality: Crystal oscillator (or divided) clock output
Can be programmed to be used as a general purpose I/O pin

In wire mode: Data input/output
Can be programmed to be used as a general purpose I/O pin
In frame mode: Interrupt request output
In wire mode: Transmit enable input
Can be programmed to be used as a general purpose I/O pin
Power supply
In wire mode: Clock output
Can be programmed to be used as a general purpose I/O pin
Ground
Power-up/-down input; activates/deactivates analog blocks
Can be programmed to be used as a general purpose I/O pin
If the power-up/-down functionality is handled in software and no usage as
general purpose I/O pin is planned then this pin should be tied to VDD
