ATmega128(L)

2467B–09/01

• 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.
