Figure 10. Internal Reset Routing
RESET INTERNAL 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 VDD. In case the voltage
falls below a certain threshold, it will pull down the RST_A pin.
High Voltage Reset
The HVR is related to the external VSUP voltage. In case
the voltage is above a certain threshold, it will pull down the
RST_A
pin. The reset is maskable with bit HVRE in the Reset
Mask Register. After a reset the high voltage reset is
disabled.
RESET EXTERNAL SOURCE
External Reset Pin
The microcontroller has the capability of resetting the
SMARTMOS device by pulling down the RST pin.
Reset Mask Register (RMR)
TTEST—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.
HVRE—High Voltage Reset Enable Bit
This read/write bit enables resets on high voltage
conditions. Reset clears the HVRE bit.
1 = High voltage reset enabled.
0 = High voltage reset disabled.
HTRE—High Temperature Reset Enable Bit
This read/write bit enables resets on high temperature
conditions. Reset clears the HTRE bit.
1 = High temperature reset enabled.
0 = High temperature reset disabled.
