4.3.2 Functional Description
The brown out detection of the chip will cause a reset whenever the core or IO power supply falls below the speci-
fied region. An over-voltage protection is not implemented. The circuit will not be operational when the core sup-
ply is below VDDmin. In these cases the power-on-reset will take care of proper reset generation.
4.4 Reset Generation
4.4.1 Reset Generation (RESGEN)
The IC is equipped with a reset input pin which can be used to reset the chip. Any low pulse longer than TDEBNRST
on the external reset line will be sensed and causes an IC reset.
The IC contains different dynamic and static reset sources. The static sources trigger the master reset as long as
the cause for the reset persists. The dynamic sources trigger the reset for a defined minimum reset time. After
that time has expired the system reset is released. In case the dynamic source is still signaling a reset the reset is
re-triggered.
Static reset sources:
- A power up sequence of the core voltage (power on reset)
- Brown out of the core voltage
Dynamic reset sources:
- Uncorrectable FLASH CRC error
- SRAM parity error
- CPU register parity error
- Watchdog timeout
- Uncorrectable trim register ECC error
