PRODUCTION DATA.
In this mode the output signals of both CPUs and both VIMs are compared, and a difference in the outputs is indicated by the compare_error terminal. For more details about CPU and VIM lockstep comparison, refer to the device technical reference manual.
CCM-R5F also produces a signal to ESM GP1.92 to indicate its current status whether it is out of lockstep or is in self-test mode. This ensures that any lock step fault is reported to the CPU.
