 // Dump a value via CSR
 // !!! Careful: This is only supported in simulation and an experimental
 // feature. All writes to unimplemented CSR registers will be dumped by Snitch.
 // This can be exploited to quickly print measurement values from all cores
 // simultaneously without the hassle of printf. To specify multiple metrics,
 // different CSRs can be used. The macro will define a function that will then
-// always print via the same CSR. E.g., `dump(errors, 8)` will define a function
-// with the following signature: `dump_errors(uint32_t val)`, which will print
-// the given value via the 8th register. Alternatively, the `write_csr(reg,
-// val)` macro can be used directly.
