Not production tested. 2: VDD-OUT is the voltage present at the VDD pin. VDD is the internally generated bias voltage. 3: This is the total source current for all GPIO pins combined. Individually, each pin can source a maximum of 25 mA. 4: PE1 = 0x00h, ABECON = 0x00h, ATSTCON = 0x80h, WPUGPA = 0x00h, WPUGPB = 0x00h, and SLEEP command issued to PIC core, see SECTION 16.0. |
