3.11 Reset Generation

A system reset can be generated in different ways. The first possibility is to press the user reset push button (SW1). Secondly the supply monitor will generate a reset if an unusual voltage is detected and third a reset is raised if a UART that does a reset is selected.

If a system reset is done, it will be displayed by the red reset LED (D18).

The system reset will do a simultaneous reset of the microcontroller and the FlexRay communication controller. The MCU and / or the FlexRay CC can be disconnected from the system reset signal with two jumpers.

The Reset push button can be used in two modes:

no delay of Reset

press Reset button 2s

The selection is done by solder Jumper JP96.

JP52 Connects the FlexRay CC to the system reset signal (SK91F467-FLEXRAY) JP54 Connects the MCU to the system reset signal

Default: grey

Table 3-22: Reset Connections

The triple supply monitor on-board has the possibility to watch 5V, 3.3V and the third voltage is user configurable 2.5V or 1.8V. If any voltage has a failure, a system reset will be done.

Table 3-23: Supply Monitor Settings

By default 2.5V supply will be monitored.

The system reset also can be done via any UART. Therefore the user has the possibility to select one of the three on-board UARTs.
