6.4.2
Asynchronous external RESET pin
The RESET pin is both an input and an open-drain output with integrated RON weak pull-up
resistor. This pull-up has no fixed value but varies in accordance with the input voltage. It
can be pulled low by external circuitry to reset the device. See Electrical Characteristic
section for more details.
A RESET signal originating from an external source must have a duration of at least
therefore the MCU can enter reset state even in Halt mode.
The RESET pin is an asynchronous signal which plays a major role in EMS performance. In
a noisy environment, it is recommended to follow the guidelines mentioned in the electrical
characteristics section.
6.4.3
External Power-on reset
If the LVD is disabled by option byte, to start up the microcontroller correctly, the user must
ensure by means of an external reset circuit that the reset signal is held low until VDD is over
the minimum level specified for the selected fCLKIN frequency.
A proper reset signal for a slow rising VDD supply can generally be provided by an external
RC network connected to the RESET pin.
6.4.4
Internal low voltage detector (LVD) reset
Two different reset sequences caused by the internal LVD circuitry can be distinguished:
●
Power-on reset
●
Voltage Drop reset
The device RESET pin acts as an output that is pulled low when VDD<VIT+ (rising edge) or
The LVD filters spikes on VDD larger than tg(VDD) to avoid parasitic resets.
