Data Sheet

When reading from this register, the 8 MSBs (Bit 15 to Bit 8) are

read first from Register Address 0x08 (T_CRITsetpoint most

significant byte register), and then the 8 LSBs (Bit 7 to Bit 0) are

read from Register Address 0x09 (T_CRITsetpoint least significant

byte register). Only Register Address 0x08 (T_CRITsetpoint most

significant byte register) must be loaded into the address pointer

Address 0x09 (T_CRITsetpoint least significant byte register).

T_CRITSETPOINT REGISTERS

The T_CRITsetpoint most significant byte register and the T_CRIT

setpoint least significant byte register store the critical

overtemperature limit value. A critical overtemperature event

occurs when the temperature value stored in the temperature

value register exceeds the value stored in this register. The CT pin

is activated if a critical overtemperature event occurs. The

temperature is stored in twos complement format with the

MSB being the temperature sign bit.

The default setting for the T_CRITsetpoint register is 147°C.
