10.5. Disabling Secondary Device Functions
The LED Drivers, weak pull-ups, and V
supply current for the V
the MOTEN and MUXEN pins are tied to ground, but will cause the address and data pins to float (causing
undefined device behavior and increased power consumption) if they are not externally driven or pulled to a
defined logic level using pull-up or pull-down resistors. The internal weak pull-ups should not be disabled unless all
digital pins are externally driven to a logic high or logic low state.
