Alternate Functions of
Port C
2466T–AVR–07/10
The Port C pins with alternate functions are shown in
the pull-up resistors on pins PC5(TDI), PC3(TMS) and PC2(TCK) will be activated even if a reset
occurs.
Table 28. Port C Pins Alternate Functions
The alternate pin configuration is as follows:
• TOSC2 – Port C, Bit 7
TOSC2, Timer Oscillator pin 2: When the AS2 bit in ASSR is set (one) to enable asynchronous
clocking of Timer/Counter2, pin PC7 is disconnected from the port, and becomes the inverting
output of the Oscillator amplifier. In this mode, a Crystal Oscillator is connected to this pin, and
the pin can not be used as an I/O pin.
• TOSC1 – Port C, Bit 6
TOSC1, Timer Oscillator pin 1: When the AS2 bit in ASSR is set (one) to enable asynchronous
clocking of Timer/Counter2, pin PC6 is disconnected from the port, and becomes the input of the
inverting Oscillator amplifier. In this mode, a Crystal Oscillator is connected to this pin, and the
pin can not be used as an I/O pin.
• TDI – Port C, Bit 5
TDI, JTAG Test Data In: Serial input data to be shifted in to 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.
• TDO – Port C, Bit 4
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.
The TD0 pin is tri-stated unless TAP states that shifts out data are entered.
• TMS – Port C, Bit 3
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.
• TCK – Port C, Bit 2
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.
