Serial Timing Diagram
Programming Model
The ISL59532 is configured by a series of 16-bit serial control words. The three MSBs (B15-13) of each serial word determine the
basic command:
Mapping Inputs to Outputs
Inputs are mapped to their desired outputs using the input/output control word. Its format is:
I4:I0 form the 5 bit word indicating the input channel (0 to 31), and O4:O0 determine the output channel which that input channel will
map to. One input can be mapped to one or multiple outputs. To fully program the ISL59532, 32 INPUT/OUTPUT words must be
transmitted - one for each input channel.
Note: Broadcast Mode must be disabled when configuring input/output mapping. INPUT/OUTPUT words transmitted while in
Broadcast Mode will not be processed correctly and result in corrupt channel mapping when Broadcast Mode is disabled.

SLATCH falling edge timing/placement is a “don’t care.”
Serial data is latched only on rising edge of SLATCH.

SDO = SDI delayed by 15.5 SCLKs to allow daisy-chaining of multiple ISL59532s. SDO changes on the falling edge of SCLK.
