4 Connecting to the Device

The PIC32 family provides two possible physical interfaces for connecting and programming the memory contents, see Figure 4-1. For all programming interfaces, the target device must be powered and all required signals must be connected. In addition, the interface must be enabled, either through its Configuration bit, as in the case of the JTAG Four-Wire interface, or though a special initialization sequence, as is the case for the Two-Wire ICSP™ interface.

The JTAG interface is enabled by default in blank devices shipped from the factory.

Enabling ICSP is described in Entering Two-Wire Enhanced ICSP Mode.
