• A13/TMS/PCINT13 – Port C, Bit 5
A13, External memory interface address bit 13.
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.
PCINT13: The pin can also serve as a pin change interrupt.
• A12/TCK/PCINT12 – Port C, Bit 4
A12, External memory interface address bit 12.
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.
PCINT12: The pin can also serve as a pin change interrupt.
• A11/PCINT11 – Port C, Bit 3
A11, External memory interface address bit 11.
PCINT11: The pin can also serve as a pin change interrupt.
• A10/PCINT10 – Port C, Bit 2
A10, External memory interface address bit 10.
PCINT11: The pin can also serve as a pin change interrupt.
• A9/PCINT9 – Port C, Bit 1
A9, External memory interface address bit 9.
PCINT9: The pin can also serve as a pin change interrupt.
• A8/PCINT8 – Port C, Bit 0
A8, External memory interface address bit 8.
PCINT8: The pin can also serve as a pin change interrupt.
Table 36 and Table 37 relate the alternate functions of Port C to the overriding signals
shown in Figure 32 on page 67.
