M
(
CS
), data clock (SCLK), and data in (DIN). Drive
CS
low to enable the serial interface and clock data syn-
chronously into the shift register on each SCLK rising
edge.
The WRITE commands (C1, C0 = 00 or 01) require 16
clock cycles to clock in the command and data (Figure
2a). The COPY commands (C1, C0 = 10, 11) can use
either eight clock cycles to transfer the command bits
(Figure 2b) or 16 clock cycles with 8 data bits that are
disregarded by the device (Figure 2a).
Table 1. Register Map
After loading data into the shift register, drive
CS
high
to latch the data into the appropriate potentiometer
control register and disable the serial interface. Keep
CS
low during the entire serial-data stream to avoid
corruption of the data.
The serial-data timing for the potentiometer is shown in
Figures 1 and 2.
