AC244035, AC244036
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 these headers,
use the following information.
Header Setup and Operation
For this header, set up the jumpers as described below.
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.
