35.2. C2CK Pin Sharing
The C2CK pin is shared with the RST signal on this device family. If the RST pin is used by other parts of
the system, debugging and programming the device can still be accomplished without disrupting the rest of
the system. If this is desired, it is normally necessary to add a resistor to isolate the system’s reset line
from the C2CK signal. This external resistors would not be necessary for production boards, where debug-
ging capabilities are not needed. A typical isolation configuration is shown in Figure 35.1.
The configuration in Figure 35.1 assumes the RST pin on the target device is used as an input only. Addi-
tional resistors may be necessary depending on the specific application.
