Header Identification

The AC number is used for ordering the Processor Extension Pak, which contains the

debug header. However, this number is not on the header, as the board may be used

for multiple headers by inserting different -ICE/-ICD devices. To identify this header,

use the following information.

Header Setup and Operation

For the PIC16F690 20-pin header, you will need to set the S1 switches (Figure 2-6) to

enable peripherals and choose devices (Table 2).

Header Limitations

Sometimes a header device (-ICE/-ICD) has operational issues or errata. To determine

if a device on a header has limitations, see your hardware tool documentation.
