Alternate Functions of Port F
4250C–CAN–03/04
RXD0, USART0 Receive Pin. Receive Data (Data input pin for the USART0). When the
USART0 receiver is enabled this pin is configured as an input regardless of the value of
DDRE0. When the USART0 forces this pin to be an input, a logical one in PORTE0 will
turn on the internal pull-up.
Table 42 and Table 43 relates the alternate functions of Port E to the overriding signals
shown in Figure 33 on page 68.
Table 42. Overriding Signals for Alternate Functions PE7..PE4
Table 43. Overriding Signals for Alternate Functions in PE3..PE0
Note:
The Port F has an alternate function as analog input for the ADC as shown in Table 44.
If some Port F pins are configured as outputs, it is essential that these do not switch
when a conversion is in progress. This might corrupt the result of the conversion. If the
