CHECK (CRC)

1. PTA2 and PTA3 operate as true-open drain when working as output.

2. PTA4/ACMPO/BKGD/MS is an output-only pin when used as port pin.

3. PTD0, PTD1, PTB4 and PTB5 can provide high sink/source current drive.

4. The secondary power pair of VDD and VSS (pin 11, 27 and 28 in 44-pin package) are not bonded in 32-pin, 20-pin or 16-pin packages.
