SWAS037 – JANUARY 2019
(1)
I = input
O = output
RF = radio frequency
I/O = bidirectional
(2)
This pin has dual functions: as a SOP[2] (device operation mode), and as an external TCXO enable. As a TXCO enable, the pin is an output on power up and driven logic high. During
hibernate low-power mode, the pin is in a Hi-Z state but is pulled down for SOP mode to disable TCXO. Because of the SOP functionality, the pin must be used as an output only.

I
Hibernate signal input to the NWP subsystem
(active low). This is connected to the MCU GPIO. If
the GPIO from the MCU can float while the MCU
enters low power, consider adding a pullup resistor
on the board to avoid floating.
