10-Port Constant-Current LED Drivers and I/O
Expanders with PWM Intensity Control
The MAX6966/MAX6967 contain 16 internal registers,
addressed as 0x00–0x09, and 0x10–0x15, which con-
figure and control the peripheral
addresses, 0x0E and 0x0F, do not store data but return
the port input status when read. Four virtual addresses,

0x0A–0x0D allow more than one register to be written
with the same data to simplify software. The no-op
address, 0x20, causes no action when written or read,
and is used as a dummy register when accessing one
MAX6966/MAX6967 out of multiple cascaded devices.
