Description
Active low reset of entire circuit. Should be applied before doing
anything else.
Reserved, write as 0.
Forces the frequency synthesiser on (starts with a calibration).
The synthesiser can also be turned on in a number of other
ways.
Selects whether RX operation ('0') or TX operation ('1') is desired
when FS_FORCE_EN is used. RX or TX mode is usually
selected using the SRX and STX strobe commands (or RX and
TX pins).
Reserved, write as 0.

Bypasses the 16 MHz main crystal oscillator and uses a buffered
version of the signal on Q1 directly. Used for external clock only.
Forces the 16 MHz main crystal oscillator and the global bias on.
These modules can also be turned on in other ways.
