Table 27. REGISTER 0DH, INTERNAL TEMPERATURE THERM LIMIT (POWER-ON DEFAULT, 37H 555C)

Bit

Name

R/W

Description

7–0

Int Temp THERM Limit

R/W

This register contains the THERM limit for the internal temperature channel.

Exceeding this limit causes the THERM output pin to be asserted.

Bit

Name

R/W

Description

7–0

TDM1 THERM Limit

R/W

This register contains the THERM limit for the TDM1 temperature channel.

Exceeding this limit causes the THERM output pin to be asserted.
