 _Also proposed was to simply allocate a range of `siselect` values that serve to select the trigger, bypassing `tselect` when accessing trigger state through `sireg*`.  This adds no new CSRs, but artificially limits the number of triggers accessible in S-mode.  `tselect` supports up to 2^MXLEN^ triggers, while `siselect` would likely allocate only enough values to cover practical implementations (256?)._

+_Other approaches considered:_

 * _Define new `stdata[123]` and `stinfo` registers, which provide S-mode access to `tdata[123]` and `tinfo`.  Avoids dependence on Sscsrind altogether, but costs 4 more CSR addresses._

 * _Access `tselect` via `sireg5` instead of through a new `stselect` CSR (access to `tdata*` and `tinfo` is the same as spec'd above).  While saving a CSR, this approach would require `sireg5` to continue to access `tselect` while the other `sireg*` registers shift the state they acccess based on the `tselect` value.  This approach seems more awkward for implementation._
