– 63 basic instructions

– 17 main addressing modes

– 8 x 8 unsigned multiply instruction

– True bit manipulation

■ 3 Timers

– Configurable watchdog timer

– Two 16-bit timers with: 2 input captures, 2 out-

put compares, external clock input on one tim-

er, PWM and Pulse generator modes (one

only on ST72104Gx-Auto and ST72216G1-

Auto)
