2570M–AVR–04/11
• 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.
