Table 9-20.
The status register indicates the current status of the transceiver and is readable via the 4-wire
serial interface. Setting Power_On or P_On_Aux or an event on ST1, ST2, ST3, ST4 or ST5 is
indicated by an IRQ.
Reading the status register resets the bits Power_On, Low_Batt, P_On_Aux and the IRQ
