Function
Software Register Reset Bit.
This bit may be used to reset all registers simultaneously to a DEFAULT state,
7
swres
without the need for sequentially writing to each individual register. The RESET
is accomplished by setting swres = 1. This bit will be automatically cleared.
Enable Low Battery Detect.
6
enlbd
When this bit is set to 1 the Low Battery Detector circuit and threshold
comparison will be enabled.
Enable Wake-Up-Timer.
Enabled when enwt = 1. If the Wake-up-Timer function is enabled it will operate
5
enwt
in any mode and notify the microcontroller through the GPIO interrupt when the
timer expires.

rxon
Automatically cleared if Multiple Packets config. is disabled and a valid packet
received.
TUNE Mode (PLL is ON).
