Data Transmit Sequence Through the SDI Pin
Note:
Do not send CLK pulses with the TX data bits, otherwise they will be interpreted as commands.
This mode is not SPI compatible.
If the crystal oscillator and the PLL are running, the tsx+tsp delay is not needed.

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).
