3.2.3 Target Power

There are two methods for externally powering the target:

• Externally Powered Through Target
• Externally Powered Through Debugger

In the following descriptions, only three lines are active and relevant to core debugger operation: pins 1 (V_PP/MCLR), 5 (PGC), and 4 (PGD). Pins 2 (V_DD) and 3 (V_SS) are shown in Figure 3-3 for completeness.

When providing power to the target device, ensure that the target is not exposed to voltages higher than the device V_DD rating.

Absolute maximum ratings for the device V_DD must not be exceeded. Exposure to the maximum rating conditions for any length of time may affect device reliability.

Functional operation of the device at conditions above the parameters indicated in the device data sheets specification is not recommended.

See the device data sheet for required device voltage levels and maximum ratings.
