Does anyone know what the base address is for the special purpose registers for the MPC5777C? I am working with a data acquisition device for XCPonETH and want to make use of the synced timestamp feature but this requires providing the config file for the device with the address for the time base. The time base is being read from SPR 284. Any help would be greatly appreciated. Thanks!
Hi,
SPR registers have no base address. It is not memory mapped register.
Instead you will use mfspr and mtspr instructions.
