THREE-WIRE INTERFACE (SPI, MODE (PIN 28) = LOW)
All write operations for the serial control port use 16-bit data words.
Figure 30
shows the control data word
format. The most-significant bit must be 0. There are seven bits, labeled IDX[6:0], that set the register address
for the write operation. The least-significant eight bits, D[7:0], contain the data to be written to the register
specified by IDX[6:0].

Figure 31
shows the functional timing diagram for writing to the serial control port. To write the data into the
mode register, the data is clocked into an internal shift register on the rising edge of the MC clock. The serial
data should change on the falling edge of the MC clock, and MS should be LOW during write mode. The rising
edge of MS should be aligned with the falling edge of the last MC clock pulse in the 16-bit frame. MC can run
continuously between transactions while MS is in the LOW state.
