FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Figure 11. Internal Reset Routing
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)
High Temperature Reset Test (TTEST)
This read/write bit is for test purposes only. It decreases
the over-temperature shutdown limit for final test. Reset
clears the HTRE bit.
1 = Low temperature threshold enabled
0 = Low temperature threshold disabled
High Voltage Reset Enable Bit (HVRE)
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
High Temperature Reset Enable Bit (HTRE)
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
