Conditions

Note 1:

Ensured by design. Not production tested.

VDD-OUT is the voltage present at the VDD pin. VDD is the internally generated bias voltage.

This is the total source current for all GPIO pins combined. Individually, each pin can source a maximum of

25 mA.

PE1 = 0x00h, ABECON = 0x00h, ATSTCON = 0x80h, WPUGPA = 0x00h, WPUGPB = 0x00h, and

SLEEP command issued to PIC core, see SECTION 16.0.
