Software Register Reset Bit.
This bit may be used to reset all registers simultaneously to a DEFAULT state, 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.
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 in any
mode and notify the microcontroller through the GPIO interrupt when the timer expires.

Automatically cleared if Multiple Packets config. is disabled and a valid packet received.
TUNE Mode (PLL is ON).
When pllon = 1 the PLL will remain enabled in Idle State. This will for faster turn-around
time at the cost of increased current consumption in Idle State.
