2 / 90 page  2 3547F–MICRO–6/06 AT89LP2052/LP4052 The two timer/counters in the AT89LP2052/LP4052 are enhanced with two new modes. Mode 0 can be configured as a variable 9- to 16-bit timer/counter and Mode 1 can be configured as a 16-bit auto-reload timer/counter. In addition both timer/counters may be configured as 8-bit Pulse Width Modulators with 8-bit prescalers. The I/O ports of the AT89LP2052/LP4052 can be independently configured in one of four oper- ating modes. In quasi-bidirectional mode, the ports operate as in the classic 8051. In input mode, the ports are tri-stated. Push-pull output mode provides full CMOS drivers and open-drain mode provides just a pull-down. 2.
