Serial peripheral interface communication system and method

A method of serial peripheral interface (SPI) communication, the method comprising:

• transmitting a data packet from a master device to a slave device, wherein:
• the data packet includes a read register address, a write register address, and write data, and
• the read register address and the write register address correspond to a data register of a plurality of data registers of the slave device;
• receiving a portion of the data packet at the slave device, wherein the portion of the data packet includes the read register address;
• reading the read register address in the data packet at the slave device;
• and
• transmitting, from the slave device, data from the data register corresponding to the read register address of the slave device to the master device after the read register address has been read,
• wherein transmitting the data from the slave device to the master device and transmitting the write data from the master device to the slave device occur simultaneously.
