Debug Interface
The CP6003-SA provides several onboard options for hardware and software debugging, such as:
•
Four bicolor General Purpose LEDs (LED0..3), which indicate hardware failures, uEFI
BIOS POST codes and user-configurable outputs
•
A JTAG connector, J16, for programming the onboard logic
•
An XDP-SFF, processor JTAG connector, J25, for facilitating the debug and uEFI BIOS
software development

CompactPCI Interface
The CP6003-SA supports a flexibly configurable, hot swap CompactPCI interface. In the sys-
tem slot the PCI/ PCI-X interface is in the transparent mode, and in the peripheral slot the Com-
pactPCI interface is isolated so that it cannot communicate with the CompactPCI bus. This
mode is known as "passive mode".
2.10.11.1 Board Functionality when Installed in System Slot
In a system slot, the CompactPCI interface can be either a 64-bit/66 MHz PCI or PCI-X inter-
face via a dedicated PCI Express-to-PCI-X bridge from Pericom (PI7C9X130).
The CP6003-SA supports up to seven peripheral slots with 33 MHz and up to 4 peripheral slots
with 66 MHz through a backplane.
The PCI Express-to-PCI-X bridge detects the PCI mode (PCI or PCI-X) and the bus speed (33
MHz or 66 MHz) via two PCI control signals on J1: PCIXCAP (pin B16) and M66EN (pin D21).
The following configurations are supported by the CompactPCI interface.

Note ...
To support 66 MHz PCI/PCI-X frequency, the CompactPCI signaling voltage
(VI/O) must be 3.3 V.
The CP6003-SA provides automatic voltage detection for the VI/O to switch the
PCI frequency to 33 MHz in an 5V environment.
