Effect of the Different Reset Events
Table 7-4 on page 52
The cause of the last reset can be read from the RCAUSE register. This register contains one bit
for each reset source, and can be read during the boot sequence of an application to determine
the proper action to be taken.
The Power-On Detector monitors the VDDCORE supply pin and generates a reset when the
device is powered on. The reset is active until the supply voltage from the linear regulator is
above the power-on threshold level. The reset will be re-activated if the voltage drops below the
power-on threshold level. See Electrical Characteristics for parametric details.
The Brown-Out Detector (BOD) monitors the VDDCORE supply pin and compares the supply
voltage to the brown-out detection level, as set in BOD.LEVEL. The BOD is disabled by default,
but can be enabled either by software or by flash fuses. The Brown-Out Detector can either gen-
erate an interrupt or a reset when the supply voltage is below the brown-out detection level. In
any case, the BOD output is available in bit POSCSR.BODDET bit.
Note that any change to the BOD.LEVEL field of the BOD register should be done with the BOD
deactivated to avoid spurious reset or interrupt.
See Electrical Characteristics chapter for parametric details.
