14 Pattern Match Engine (PME) Pin Interrupt generator 8 pins can be selected to generate interrupts to the core Pattern match feature The same 8-pins (above) can be selected from all GPIO pins to contribute to a Boolean expression Example: (IN0)~(IN1)(IN3)^ + (IN1)(IN2) + (IN0)~(IN3)~(IN4) The PME keeps polling these pins and generates an interrupt to the core when one or more of the bit slices match IN0 IN1 IN2 IN3 IN4 IN5 IN6 IN7 Pattern Match Engine O/P Both the pin interrupt and pattern match blocks are mutually exclusive

Memories are in stand-by mode. The WWDT, WKT, and BOD can remain active to wake up the system on an interrupt Peripherals receive no internal clocks. The flash memory is powered down. The WWDT, WKT, and BOD can remain active to wake up the system on an interrupt The entire system is shut down except for the general purpose registers in the PMU and the self wake-up timer. All registers maintain their internal states. The part can wake up on a pulse on the WAKEUP pin or when the self wake-up timer times out. On wake-up, the part reboots
