the module to avoid welding short circuit。
d. The MCU is used to drive software, which can communicate with other modules。
Warning: after all equipment has been installed, switch on power。
Ten.Communication Interface
SPI time-sequential format
Notes:
1. SPI to drop along sampling data，rise along the change data；MCU under control
SPI_MOSI be bound after SPI_CLK raise that to change the data。
2. SPI read write bit： write=0，read=1。
3. The access to FIFO register 0X28 can be read by byte. Access to multiple FIFO data can be
used with a SPI_ CS cycle.
4. When accessing other registers except FIFO, one reads and reads 16bits.
5.When accessing multiple registers except FIFO, you can use a SPI CS cycle. At this point, the
address will only be written once, then the 16bit data, and the chip will automatically increase
the register address when a register value is written.
