EPXA10 Development Board Hardware Reference Manual
To design a matching daughter board, designers must do one of the
following:
■ Base designs on the SOLC expansion header dimensions given in
Figure 8 on page 31
■ Translate dimensions from the TOLC motherboard dimensions
LED & Switch Interfaces
The EPXA10 development board provides a variety of LED and switch
interfaces.
LED Interface
The development board has eight LEDs that are used for application-
specific functions on the EPXA10 device. Table 54 on page 63 provides
more information on EPXA10 device pins connected to LEDs.
User-Defined LEDs
The EPXA10 development board provides eight user-definable LEDs,
which connect directly to the EPXA10 device I/O pins. The LEDs can be
used for any kind of application.
Table 25 lists the interface characteristics for the user-defined LED
interfaces.
LEDs are also used for specific application functions, such as the
configuration, RS-232 and Ethernet interfaces. Table 26 on page 34 lists the
application-specific LEDs, their power supply status, and their functions.
