Notes:
1. The I_IO current sunk must always respect the absolute maximum rating specified in Section 11.2.2 and the sum of I_IO
(I/O ports and control pins) must not exceed I_VSS.
2. The I_IO current source must always respect the absolute maximum rating specified in Section 11.2.2 and the sum of
I_IO (I/O ports and control pins) must not exceed I_VDD. True open drain I/O pins does not have V_OH.
