In the existing code, the SHIM_SYNC::SYNC_GO bit is set, and the code waits for it to return to zero. That second wait part is just wrong: the SYNC_GO bit is *write-only* so there's no way to know if it's cleared by hardware. The code works because the value for a read-only bit is zero, but that's really just luck. Simplify the sequence to a plain read-modify-write.
