Alternate Functions of Port F
Table 13-17. 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
some Port F pins are configured as outputs, it is essential that these do not switch when a con-
version 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.

• 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 Reg-
ister (scan chains). When the JTAG interface is enabled, this pin can not be used as an I/O pin.
