3.2 Peripheral Multiplexing on I/O lines
3.2.1
Multiplexed Signals
Each GPIO line can be assigned to one of the peripheral functions. The following tables (Section
3-1 ”100-pin GPIO Controller Function Multiplexing” on page 19 to Section 3-4 ”48-pin GPIO
Controller Function Multiplexing” on page 28) describes the peripheral signals multiplexed to the
GPIO lines.
Peripheral functions that are not relevant in some parts of the family are grey-shaded.
For description of differents Supply voltage source, refer to the Section 6. ”Power and Startup
Considerations” on page 46.
