7.6.4 Temperature High Limit Register (P[1:0] = 11) [reset = 3C00h]

The temperature high limit register is used to store the high temperature threshold for the device high limit flag.

The default power up reset value is +60 °C. The power on default value is valid only when ETM = 0. At the end

of each temperature conversion, the device compares the temperature result with the temperature high limit

register. If the temperature result is greater than the threshold set in this register, the FH bit in the configuration

register is set.

When the ETM bit in the configuration register is updated, it is strongly recommended that the user update the

high limit register.

Note

When the ETM bit is set to 0, any writes to the EM bit will be ignored.
