The Critical Alarm Event activates the separate T_CRIT_A output. Typically, this would feed circuitry separate
from the processor on the assumption that if the system reached this temperature, the processor might not be
responding.
Note: Event Interrupt mode is drawn as if the user is reading the part. If the user doesn't read, the outputs would go
low and stay that way until the LM77 is read.
