6.3.3 SPI Write
Figure 7. SPI Write protocol
The SPI Write command consists of 16 clock pulses.
6.3.4 SPI Read in 3-wire mode
3-wire mode is entered by setting SIM mode (SPI Serial Interface Mode selection) in CTRL_REG2.
Figure 8. SPI Read protocol in 3-wire model
The SPI Read command consists of 16 clock pulses:
– bit 1-7: address AD(6:0). This is the address field of the indexed register.
– bit 8-15: data DO(7:0) (read mode). This is the data that will be read from the device (MSB first).
– bit 0: WRITE bit. The value is 0.
– bit 1-7: address AD(3:0). This is the address field of the indexed register.
– bit 8-15: data DI(7:0) (write mode). This is the data that will be written inside the device (MSB first).
– bit 0: READ bit. The value is 1.
– bit 1-7: address AD(6:0). This is the address field of the indexed register.
– bit 8-15: data DO(7:0) (read mode). This is the data that will be read from the device (MSB first).
