2.3.6
JTAG Interface
Two JTAG connectors, the in-circuit emulation (ICE) connector and a stake pin header, provide the
interface for devices on the JTAG chain, such as the main board and Intel
®
PXA270 Processor
CPLDs, the main board FPGA, and the daughter card. For details of the JTAG interface, see
and the daughter card schematic diagram.
2.3.7
Logic-Analyzer Interface
lists the logic-analyzer connections on the daughter card. For pin assignments, see the
daughter card schematic diagram.
2.3.8
System Configuration Register
Pull-up and pull-down resistors built into the daughter card provide the system with the necessary
configuration information. For details of the System Configuration Register, see
“Virtual Configuration Registers” on page 50
.
2.3.9
Connectors
lists all of the connectors on the daughter card.
•
For the locations
of connectors on the daughter card, see
