11.5   Lower Alarm Trip Register (16-bit Read/Write, Address = 03h)
The Lower Alarm Trip Register holds the user programmed lower temperature boundary trip point in 11-bit twos
complement format (0.25癈 resolution) that can be used to monitor ambient temperature in an operating window (See
Table 11-9 and Table 11-10). When temperature decreases below this trip point minus any hysteresis set or increases to 
meet or exceed this trip point, then the
EVENT pin is asserted (if enabled).
This register becomes read-only if the Alarm Window Lock bit (WINLOCK) bit six in the Configuration register is set to a
one.
