2548E–AVR–07/06
• TMS/PCINT10 – Port B, Bit 2
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.
PCINT10, Pin Change Interrupt Source 10. The PB2 pin can serve as external interrupt source
to the MCU.
• TDI/PCINT9 – Port B, Bit 1
TDI, JTAG Test Data Input: Serial input data to be shifted in the Instruction Register or Data
Register (scan chains). When the JTAG Interface is enabled, this pin can not be used as I/O pin.
PCINT9, Pin Change Interrupt Source 9. The PB1 pin can serve as external interrupt source to
the MCU.
• TDO/PCINT8 – Port B, Bit 0
TDO, JTAG Test Data Output: 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.
PCINT8, Pin Change Interrupt Source 8. The PB0 pin can serve as external interrupt source to
the MCU.
