Alternate Functions of
Port F

ATmega128
Table 41. Overriding Signals for Alternate Functions in PE3..PE0
The Port F has an alternate function as analog input for the ADC as shown in
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. In ATmega103 compatibility mode
Port F is input only. 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 Reg-
ister (scan chains). When the JTAG interface is enabled, this pin can not be used as an I/O pin.
• TDO, ADC6 – Port F, Bit 6
ADC6, Analog to Digital Converter, Channel 6
TDO, JTAG Test Data Out: Serial output data from Instruction Register or Data Register. When
the JTAG interface is enabled, this pin can not be used as an I/O pin.
The TDO pin is tri-stated unless TAP states that shift out data are entered.
• TMS, ADC5 – Port F, Bit 5
ADC5, Analog to Digital Converter, Channel 5
