11. Status Register Read Command
With this command, it is possible to read the chip’s status register through the nIRQ pin. This command clears the last serviced interrupt and
processing the next pending one will start (if there is any).
12. PLL Setting and Reset Mode Command
Bits 7-6 <bw1 : bw0> select the PLL bandwidth:
Bit 1 (dr): Disables the highly sensitive RESET mode. If this bit is cleared, a 600 mV glitch in the power supply may cause a system reset. For
more detailed description see the Reset modes section.
