Note 1: Ensured by design. Not production tested.
2: V
DD-OUT
is the voltage present at the V
DD
pin. V
DD
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.
