Notes
1. I
2. This maximum applies at all times, including during power switching, and must be accounted for in power supply
3. No more than 6 (any 6) of these 10 high current outputs may be used at the V
4. The specified current rating applies when any of these pins is used as a Pulse Width Modulated (PWM) output.
5. The capacitance of pins P0.0 and P0.7 for the 87C055 exceeds 10 pF; for P0.0 this is maximum 40 pF, while for P0.7
