• Low power consumption–40 mW (typical)
• Three standby modes
– Stop—2 A (typical)
– Halt—0.8 mA (typical)
– Low voltage
• Special architecture to automate both generation and reception of complex
pulses or signals:
– One programmable 8-bit counter/timer with two capture registers and two
load registers
– One programmable 16-bit counter/timer with one 16-bit capture register
pair and one 16-bit load register pair
– Programmable input glitch filter for pulse reception
• Six priority interrupts
– Three external
– Two assigned to counter/timers
– One low-voltage detection interrupt
• Low-voltage detection with flag
• Programmable watch-dog/power-on reset circuits
• Two independent comparators with programmable interrupt polarity
• Mask selectable transistor pull-ups on ports 0, 2, 3
