11.6   Critical Alarm Trip Register (16-bit Read/Write, Address = 04h)
The Critical Alarm Trip Register holds the user programmed Critical Alarm temperature boundary trip point in
11-bit twos complement format (0.25癈 resolution) that can be used to monitor ambient temperature (See Table 11-11
and Table 11-12). When the temperature increases above this trip point, the
EVENT pin will be asserted (if enabled). It
will remain asserted until temperature decreases below or equal to the trip point minus any hysteresis set. This register
becomes read only if the Critical Alarm Trip Lock Bit (CRTALML) bit seven in the configuration register is set to a one.
