Operating Conditions in Boot Mode (FINE Interface)

FINE is used to communicate with the serial programmer in boot mode (FINE Interface).
Figure 31.23 shows an Example of Pin Connections in Boot Mode (FINE Interface). Table 31.9 lists Pin Handling in
Boot Mode (FINE Interface).
An example of pin connections shown in Figure 31.23 is a simplified circuit. Operations are not guaranteed in all
systems.
