The Voltage Brownout circuit can be either enabled or disabled during STOP mode.
Operations during STOP mode is set by the VBO_AO Flash option bit. See
Bits
If the device is in NORMAL or STOP mode, the Watchdog Timer can initiate a system
reset at time-out if the WDT_RES Flash option bit is programmed to 1. This is the
unprogrammed state of the WDT_RES Flash option bit. If the bit is programmed to 0, it
configures the Watchdog Timer to cause an interrupt, not a system reset, at time-out. The
WDT status bit in the reset status (RSTSTAT) register is set to 1 to signify that the reset
was initiated by the Watchdog Timer.
The RESET pin has a schmitt-triggered input and an internal pull-up resistor. Once the
RESET pin is asserted for a minimum of four system clock cycles, the device progresses
through the system reset sequence. Because of the possible asynchronicity of the system
clock and reset signals, the required reset duration may be three or four clock periods. A
