Note:

I/O pins are powered from VDD voltage except pins which can be used as SDADC inputs:

- PB2, PB10 and PE7 to PE15 I/O pins are powered from VDDSD12.

- PB14 to PB15 and PD8 to PD15 I/O pins are powered from VDDSD3. All I/O pin ground is

internally connected to VSS.

VDD mentioned in the Table 52 represents power voltage for a given I/O pin (VDD or

VDDSD12 or VDDSD3).

All I/Os are CMOS and TTL compliant (no software configuration required). Their

characteristics cover more than the strict CMOS-technology or TTL parameters. The

coverage of these requirements is shown in Figure 17 and Figure 18 for standard I/Os, and

in Figure 19 and Figure 20 for 5 V tolerant I/Os.
