I/O PORT PIN CHARACTERISTICS (Cont’d)

6.6.2 Output Driving Current

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

Notes:

1. The IIO current sunk must always respect the absolute maximum rating specified in Section 6.2.2 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 6.2.2 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.

3. Not tested in production, based on characterization results.
