*1) After power-on and passed 35ms or longer, be sure to perform a hardware reset operation (register
initialization). The system is reset by a low pulse input of 1ms (min.) and enters the normal operation
state. At this moment, the digital (DI) pins are set as follows: RSTN pin to high, TDATA pin to low,
CSN pin to high, SCLK pin to low, ACK pin to high, LOADN pin to high, TEST pin to VSS.

*2) When data 0xAA:10101010 is written to the SRST[8:0] register, a software reset is performed.
This setting initializes the registers and the operation mode is set to mode 1 (standby).
For details, refer to "Register Functions".
