During reset, all I/O registers are set to their initial values. The SRAM content is not reset. Appli-
cation execution starts from the Reset Vector. The instruction placed at the Reset Vector should
be an Absolute Jump (JMP) instruction to the reset handling routine. By default the Reset Vector
address is the lowest Flash program memory address, ‘0’, but it is possible to move the Reset
Vector to the first address in the Boot Section.
The I/O ports of the AVR are immediately tri-stated when a reset source goes active.
The reset functionality is asynchronous, so no running clock is required to reset the device.
After the device is reset, the reset source can be determined by the application by reading the
Reset Status Register.
The MCU is reset when the supply voltage VCC is below the Power-on Reset threshold voltage.
The MCU is reset when a low level is present on the RESET pin.
The MCU is reset when the Watchdog Timer period expires and the Watchdog Reset is enabled.
The Watchdog Timer runs from a dedicated oscillator independent of the System Clock. For
more details see
The MCU is reset when the supply voltage VCC is below the Brown-Out Reset threshold voltage
and the Brown-out Detector is enabled. The Brown-out threshold voltage is programmable.
