1068 - LatticeXP2: Programming and Configuration: How to configure the MCCLK_FREQ for the LatticeXP2 family in the software?
LatticeXP2: Programming and Configuration: The MCCLK_FREQ option is not supported in the ispLEVER/Lattice Diamond Spreadsheet View's Global Preference tab for the LatticeXP2 family because this preference is not required by the ispJTAG programming with the jedec file. The MCCLK_FREQ is only required by the Master SPI flash configuration when the default CCLK frequency is changed by the user.
The MCCLK_FREQ setting can be specified in the ispUFW GUI when converting the jedec file into a bitstream file for the external SPI flash configuration.
