ATmega325P/3250P

• 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.
