 > +  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.
