LatticeMico8 Processor Reference Manual 11Chapter 3Configuration OptionsThe LatticeMico8 microcontroller is reconfigurable. Table 6 outlines thevarious configuration options that are available to a designer.Table 6: LatticeMico8 Configuration OptionsParameter Name DescriptionLATTICE_FAMILY The target Lattice FPGA family.CFG_PROM_INIT_FILE Provides the file that contains the initialization data (program code) for aninternal PROM.CFG_PROM_INIT_FILE_FORMAT Indicates whether CFG_PROM_INIT_FILE is in hex (default) or binary.CFG_PROM_SIZE Indicates the number of instructions that can be accommodated in thePROM.CFG_SP_INIT_FILE Provides the file that contains the initialization data (program data) for aninternal scratchpad.CFG_SP_INIT_FILE_FORMAT Indicates whether CFG_SP_INIT_FILE_FORMAT is hex (default) or binary.SP_PORT_ENABLE Indicates whether the scratchpad is internal (value 1) or external (value 0).The default is 1.SP_SIZE Indicates the number of bytes in the scratchpad.SP_BASE_ADDRESS Provides the base address of the scratchpad, regardless of whether it isinternal or external.CFG_IO_BASE_ADDRESS Provides the base address of the peripheral memory region.CFG_EXT_SIZE_[8|16|32] Indicates the size of address bus for the scratchpad and peripheral memoryregions and, therefore, identifies the LatticeMico8 memory mode. Thedefault is 16 (medium memory mode).CFG_REGISTER_[16|32] Indicates the number of general-purpose registers in LatticeMico8. Thedefault is 8.
