LFOSC_CAL1_EN
Enable LFOSC Calibration 1, the calcultion
will only be done once after the power is on
or reset. Ensure that the frequency of the
LFOSC is roughly adjusted to 32 kHz. This
calculation will cost 5 milliseconds.
0：Disable
1：Enable
5
RW
LFOSC_CAL2_EN
Enable LFOSC Calibration 2, the calcultion
will be runing continuously in the RX or TX
status ， Ensure that the frequency of the
LFOSC is more accurate adjusted to 32
kHz.. This correction is done in parallel in the
TX or RX status. The enabling condition is
that the LFOSC_CAL1_EN must be enabled.

TX_EXIT_STATE<1:0>
Automatically exit to the preset status after
transmitting,it is only valid in the packet
mode. otherwise, the chip will not
automatically exit from the TX status, but
wait for the MCU to send go_* command to
switch.
