Header Identification
The header AC number is used for ordering the header. However, this number is not
on the debug header, as the board is often used for multiple headers by inserting
different ICE/ICD devices. To identify this debug header, use the following information.

Header Setup and Operation
For the PIC16F690 20-pin header, you will need to set the S1 switches (Figure 6) to
enable peripherals and choose devices (Table 2).
