ADVANCE INFORMATION
R5FSS: Lock-Step Mode of Operation is Not
Functional
R5FSS cannot operate in lock-step mode due to a hardware issue with the VIM (Vectored Interrupt Manager) module inside it. If the VIM module is active in lock-step mode, it may go out of lock-step erroneously, causing the generation of spurious lock-step miscompare interrupts towards the Safety monitor in the SoC. Additionally, this can cause the second core in the R5FSS to lock-up completely. The first core will continue to execute and is unaffected by this issue.
There is no workaround to enable lock-step operation. R5FSS can only operate in split mode.
