MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
Reset
The 908E626 chip has four internal reset sources and one
external reset source, as explained in the paragraphs below.
Figure 7
depicts the internal reset sources.

Autonomous Watchdog
AWD modules generates a reset because of a timeout
(watchdog function).
High-Temperature Reset
To prevent damage to the device, a reset will be initiated if
the temperature rises above a certain value. The reset is
maskable with bit HTRE in the Reset Mask Register. After a
reset the high-temperature reset is disabled.
Low-Voltage Reset
The LVR is related to the internal V
DD
. In case the voltage
falls below a certain threshold, it will pull down the
RST_A
terminal.
High-Voltage Reset
The HVR is related to the external V
SUP
voltage. In case the
voltage is above a certain threshold, it will pull down the
RST_A
terminal. The reset is maskable with bit HVRE in the Reset
Mask Register. After a reset the high-voltage reset is disabled.

Reset Terminal
The microcontroller has the capability of resetting the
SMARTMOS
device by pulling down the
RST
terminal.

High-Temperature Reset Test
This read/write bit is for test purposes only. It decreases the
overtemperature shutdown limit for final test. Reset clears the
HTRE bit.
1 = Low-temperature threshold enabled.
0 = Low-temperature threshold disabled.
