Notes:

1. Data based on design simulation and/or technology characteristics, not tested in production.

2. When ICC mode is not required by the application ICCSEL/VPP pin must be tied to VSS.

Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.

Refer to I/O port characteristics for more details on the input/output alternate function characteristics (out-

put compare, input capture, external clock, PWM output...).
