ATmega169V/L

2514A–AVR–08/02

• TCK, 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.

• 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.

• TDO, 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 inter-

face 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.
