> + If set to true, then the CPU counter and the clock driver read the time CSR.
> + Set it only if the processor executes a read of the time CSR without a trap
> + and if all harts read the same value. If set to false, then in machine mode
> + the CPU counter and the clock driver read the mtime register of the CLINT.
> + The GR765 implements the time CSR, see GR765-DSUM, section 12.1.1, table 54.
