Description
7-1 Reserved
0 ETC_EN. When set to 1, the ETC internal signal is asserted if one of the following conditions is true:
• The temperature data value in Temperature Zone1 is higher than the critical limit set in the Temperature Crit-
ical Limit Zone1 register.
• A communication error with Device 1 (LM96011 or LM96010 or LM96012) occurs.
• A major SensorPath Bus failure is detected.
An asserted ETC signal turns off the Main power supply (via the Glue module). The resulting ETC signal is
disabled when the V_DD3 power is off and remains disabled until both of the following conditions are met:
• The delay time (182 ms) for enabling V_DD channels (see Section 8.5.55 on page 177) after V_DD3 power is
turned on, has elapsed.
• The temperature data in Temperature Zone1 was updated with a new value by the LMxx Sensor device
If the temperature data from Device 1 (LM96011 or LM96010 or LM96012) is not updated for 728 ms after V_DD3
power is on (see “Time-Out Function” on page 133), the HM assumes a communication error with the LMxx Sensor
device occurred and asserts ETC.
0: Disable assertion of ETC
1: Enable assertion of ETC (default)
