mode (400 kHz) and 7 or 10-bit addressing modes.

A/D Converter

The 10-bit Analog to Digital Converter, converts up to 16 channels in single-shot or

continuous conversion modes (12 channels in 100-pin devices). The minimum conversion

time is 3us.

Watchdog

The 16-bit Watchdog Timer protects the application against hardware or software failures and

ensures recovery by generating a reset.

I/O Ports

Up to 112 I/O ports (72 in 100-pin devices) are programmable as general purpose input/

output or Alternate Function.
