Control and Operation Using the 4-Wire Interface
Controlling the MAX6952 requires sending a 16-bit
word. The first byte, D15 through D8, is the command

driving CLK and CS lines in parallel (Figure 6). Data at
DIN propagates through the internal shift registers and
appears at DOUT 15.5 clock cycles later, clocked out
on the falling edge of CLK. When sending commands
to daisy-chained MAX6952s, all devices are accessed
at the same time. An access requires (16 x n) clock
cycles, where n is the number of MAX6952s connected
together. To update just one device in a daisy-chain,
the user can send the no-op command (0x00) to the

Writing Device Registers
The MAX6952 contains a 16-bit shift register into which
