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

Notes:

1. The IIO current sunk must always respects the absolute maximum rating specified in Section 12.2 and the sum of IIO

(I/O ports and control pins) must not exceed IVSS

2. The IIO sourced current must always respect the absolute maximum rating specified in Section 12.2 and the sum of IIO

(I/O ports and control pins) must not exceed IVDD.
