Figure 1. Serial Peripherial Interface (SPI)
This is an 8-bit SPI protocol used to communicate with the microcontroller in the system for setting various
operating parameters.
When CS is held high, the signals on the SCLK and SDI lines are ignored and SDO is forced into a
high-impedance state. SCLK must be low when CS is asserted low.
On each falling edge of the SCLK pulse after CS is asserted low, the new byte is serially shifted into the register.
The most significant bit (MSB) is shifted first. Only eight bits in a frame are acceptable. When a number of bits
shifted is different than the value eight, the information is ignored and the register retains the old setting.
The shift register transfers the data into a latch register after the eighth SCLK clock pulse and when CS
transitions from low to high (see Figure 1).
The function of the integration mode is to ignore any SPI frame transmission when the INT/HOLD bit = 1. In the
hold mode with INT/HOLD = 0, all necessary bytes may be transmitted.
