Alternate Functions of
Port C
2513K–AVR–07/09
The Port C pins with alternate functions are shown in
the pull-up resistors on pins PC7(TDI), PC5(TMS) and PC4(TCK) will be activated even if a reset
occurs.
Table 35. Port C Pins Alternate Functions
• A15/TDI/PCINT15 – Port C, Bit 7
A15, External memory interface address bit 15.
TDI, JTAG Test Data In: Serial input data to be shifted into the Instruction Register or Data Reg-
ister (scan chains). When the JTAG interface is enabled, this pin can not be used as an I/O pin.
PCINT15: The pin can also serve as a pin change interrupt.
• A14/TDO/PCINT14 – Port C, Bit 6
A14, External memory interface address bit 14.
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 TD0 pin drives actively. In other states the pin is pulled high.
PCINT14: The pin can also serve as a pin change interrupt.
