PIN DESCRIPTIONS, (CON’T)
XSW
The XSW pin is dedicated to an
external switch. This pin is
handled differently than the rest of
the switch matrix and is intended
to be connected to a switch
physically located on the outside of
the unit.
SW0
The SW0 pin is a dedicated input
pin for a switch.
PWR_OK
The PWR_OK is an active low pin
that monitors the battery status of
the unit. When the UR5HCSPI
detects a transition from high to
low on this pin, it will immediately
enter the STOP mode, turn the LED
off and remain in this state until the
batteries of the unit are replaced
and the signal is deasserted.
