Example for a register definition (MPC107):
Entry in the configuration file:
[REGS]
DMM1 0xFC000000 ;Embedded utility memory base address
IMM1 0xFEC00000 0xFEE00000 ;configuration registers at byte offset 0
IMM2 0xFEC00000 0xFEE00001 ;configuration registers at byte offset 1
IMM3 0xFEC00000 0xFEE00002 ;configuration registers at byte offset 2
IMM4 0xFEC00000 0xFEE00003 ;configuration registers at byte offset 3
FILE E:\cygnus\root\usr\demo\sp7450\mpc107.def
The register definition file:
