unless otherwise specified.
Notes:
1. The I
IO
current sunk must always respect the absolute maximum rating specified in Section 13.2.2 and the sum of I
IO
(I/O ports and control pins) must not exceed I
VSS
.
2. The I
IO
current sourced must always respect the absolute maximum rating specified in Section 13.2.2 and the sum of
I
IO
(I/O ports and control pins) must not exceed I
VDD
.
3. Not tested in production, based on characterization results.
