dW, debugWire channel. When the debugWIRE Enable (DWEN) Fuse is programmed and Lock
bits are unprogrammed, the debugWIRE system within the target device is activated. The
RESET port pin is configured as a wired -AND (open-drain) bi-directional I/O pin with pull-up
enabled and becomes the communication gateway between the target and the emulator.
XTAL2, Bit 0
XTAL2, Oscillator. The PC0 pin can serve as Inverting Output for internal Oscillator amplifier.
Table 11-7 and Table 11-8 relate the alternate functions of Port C to the overriding signals
Table 11-7.
