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.
