Bandgap
System RC Oscillator (RCSYS)
a BOD reset. To prevent unexpected writes to BOD due to software bugs, write access to this
register is protected by a locking mechanism. For details please refer to the UNLOCK register
description.
The BOD is powered by VDDIO and will not be powered during Shutdown sleep mode.

Rev: 1.0.1.0
The Flash memory, the BOD, and the Temperature Sensor need a stable voltage reference to
operate. This reference voltage is provided by an internal Bandgap voltage reference. This refer-
ence is automatically turned on at start-up and turned off during some sleep modes to save
power. The Bandgap reference is powered by VDDIO and will not be powered during Shutdown
sleep mode. Please refer to the Power Manager chapter for details.
Rev: 1.0.1.0
The system RC oscillator has a startup time of three cycles, and is always available except in
some sleep modes. Please refer to the Power Manager chapter for details. The system RC oscil-
lator operates at a nominal frequency of 115kHz, and is calibrated using the Calibration Value
