1.2.2 Automatically Wake from SLEEP
This mode only opens SLEEP TIMER. After automatically awakening, the chip will switch to the STBY
and wait for the MCU operation. Based on the operating principle introduced above, once the chip has
entered the SLEEP, the MCU cannot order the chip to jump out of the SLEEP. It can only wait for the sleep
counter timeout and begin operation until the SL_TMO interrupt is detected.

1.2.3 Automatically Wake from SLEEP, Automatically Enter RX
Open the RX_DC_EN, when the chip automatically wakes from SLEEP, it will not jump to STBY, but will
directly do the PLL correction and switch to the RX to receive. In this mode, the RFS status is not allowed, and
the MCU participation has been greatly reduced.
