8.32 TCRIT_Limit_Status Register (Address = 37h) [reset = 00h]
The TCRIT_Limit_Status Register contains the status bits that are set when a temperature channel's TCRIT limit
is exceeded. If any of these bits are set, the TCRIT status bit in the Status Register is also set, and the TCRIT
pin is asserted low.
Reading from the TCRIT_Limit_Status Register does not clear the bits in the register. Once the temperature
drops below TCRIT limit minus the TCRIT hysteresis, the corresponding status bit is automatically cleared. The
TCRIT bit in Status Register is also automatically cleared when all individual channel bits are cleared in the
TCRIT_Limit_Status register.
