8285E–AVR–02/2013
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.
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. In TAP states that shift out data, the TDO pin drives actively. In
other states the pin is pulled high.
TMS, ADC5 – Port F, Bit 5
ADC5, Analog to Digital Converter, Channel 5.
TMS, JTAG Test mode Select: This pin is used for navigating through the TAP-controller state machine. When the
JTAG interface is enabled, this pin can not be used as an I/O pin.
TCK, ADC4 – Port F, Bit 4
ADC4, Analog to Digital Converter, Channel 4.
TCK, JTAG Test Clock: JTAG operation is synchronous to TCK. When the JTAG interface is enabled, this pin can
not be used as an I/O pin.
ADC3 - ADC0 – Port F, Bit 3:0
Analog to Digital Converter, Channel 3-0.
Table 14-11. Port F pins alternate functions.
