Figure 14-1. Programming Block Diagram
Configuration Pins
The LatticeXP2 has one dedicated and nine dual-purpose sysCONFIG pins. The dual-purpose pins are available
as extra I/O pins if they are not used for configuration.
The configuration mode pins, along with a programmable option, controls how the LatticeXP2 will be configured.
The configuration mode pins (CFG[1:0]) are generally hard wired on the PCB and determine which configuration
mode will be used; the programmable option is accessed via preferences in Lattice ispLEVER
as HDL source file attributes, and allows the user to protect the configuration pins from accidental use by the user
or the place-and-route software. The LatticeXP2 devices also support ispJTAG for configuration, including trans-
parent readback, and for JTAG testing. The following sections describe the functionality of the sysCONFIG and
JTAG pins. Note that JTAG and ispJTAG will be used interchangeably in this document. Table 14-1 is provided for
reference.
