Chapter 9 Clocks and Reset Generator (CRGV4) Block Description
9.2.3
RESET is an active low bidirectional reset pin. As an input it initializes the MCU asynchronously to a
known start-up state. As an open-drain output it indicates that an system reset (internal to MCU) has been
triggered.
9.3
This section provides a detailed description of all registers accessible in the CRGV4.
