system is reset by a low pulse input of 1μs (min.) and enters the normal operation state. At this
moment, the digital (DI) pins are set as follows: RSTN pin to high, SCLK pin to Low, SDATA pin
to low, CSN pin to low.

*2) When data 0x03:10101010 is written to the SRST[7:0] register, software reset is performed.
This setting initializes the registers and the operation mode is set to mode 0 (power down).
After software reset is completed, this register comes to “0”.
