Alternate Functions of Port F

ATmega169/V
Table 41. 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 42.
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
JTAG interface is enabled, the pull-up resistors on pins PF7(TDI), PF5(TMS) and
PF4(TCK) will be activated even if a reset occurs.
Table 42. Port F Pins Alternate Functions
• TDI, ADC7 – Port F, Bit 7
ADC7, Analog to Digital Converter, Channel 7
TDI, JTAG Test Data In: Serial input data to be shifted in to the Instruction Register or
Data Register (scan chains). When the JTAG interface is enabled, this pin can not be
used as an I/O pin.
