AT43USB355 Interrupt Structure
Reset Sources
The AT43USB355 has four sources of reset:
Power-on Reset
– The MCU is reset when the supply voltage is below the power-on reset
threshold.
External Reset
– The MCU is reset when a low level is present on the RESETN pin for
more than 50 ns.
Watchdog Reset
– The MCU is reset when the watchdog timer period expires and the
watchdog is enabled.
USB Reset
– The AT43USB355 has a feature to separate the USB and microcontroller
resets. This feature is enabled by setting the BUS INT EN, bit 3 of the SPRSIE register. A
USB bus reset is defined as a SE0 (single ended zero) of at least 4 slow speed USB clock
cycles received by Port0. The internal reset pulse to the USB hardware and
microcontroller lasts for 24 oscillator periods.
–
Resets not separated: A USB bus reset will also reset the microcontroller.
–
Separated reset: A USB bus reset will only reset the USB hardware, while an
interrupt to the microcontroller will be generated if the BUS INT MSK bit, bit 3 of
SPRSMSK register, is also set.
