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  
shown in Figure 11-5 on page 72.
