SYSTEM FORCE AND SENSE SWITCHES
Each channel has switches to allow connection of the force
(FOHx) and sense (MEASVHx) lines to a central PMU for
calibration purposes. There is one set of SYS_FORCE and
SYS_SENSE pins per device. It is recommended that these
connections be made individually to each PMU channel.

TEMPERATURE SENSOR
An on-board temperature sensor monitors die temperature.
The temperature sensor is located at the center of the die. If the
temperature exceeds the factory specified value (130°C) or a
user programmable value, the device protects itself by shutting
down all channels and flagging an alarm through the latched,
open-drain TMPALM pin. Alarm status can be read back from
the alarm status register or the PMU register, where latched and
unlatched bits indicate whether an alarm has occurred and
whether the temperature has dropped below the set alarm
temperature. The shutdown temperature is set using the system
control register.
