ATmega162/V

• 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 interface 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 68.
