Figure 50. Typ. RPU vs. VDD

13.8.2 Output Driving Current

Subject to general operating condition for VDD, fCPU, and TA unless otherwise specified.

Notes:

1. The IIO current sunk must always respect the absolute maximum rating specified in Section 13.2 and the sum of IIO (I/

O ports and control pins) must not exceed IVSS.

2. The IIO current sourced must always respect the absolute maximum rating specified in Section 13.2 and the sum of IIO

(I/O ports and control pins) must not exceed IVDD. True open drain I/O pins does not have VOH.
