I/O PORT PIN CHARACTERISTICS (Cont’d)
13.8.2 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 13.2.2 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 13.2.2 and the sum of
IIO (I/O ports and control pins) must not exceed IVDD.
3. Not tested in production, based on characterization results.
