FCircuit operation
The BH3532FS has two 22k
tems which can be set in 256 steps (86 intervals).
Resistance can be set in 256 steps using the MSB first
8-bit data.
Input data is 17-bit serial data. The first bit is always “L”.
The next eight bits set the resistance for wiper 1. The last
eight bits set the resistance for wiper 0.

Input data is effective when the EN terminal is set to “H”,
and is put on hold when the EN terminal is set to “L”. Also,
the reading of the data is performed when CLK rises.
When input data is effective, the previous output data is
output serially to the DOUT terminal.
See the figures below for more details.
