Alternate Functions of

Port F

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. 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.

• 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.
