     SPIN(1prom)         UMIPS-V Reference Manual          SPIN(1prom)



     NAME
          spin - diagnostic reference pattern generator

     SYNOPSIS
          spin [[ -c count ] [ -v value ] -(r|w)(b|h|w) address ]+ [
          -c count ]

     DESCRIPTION
          spin generates reference patterns for diagnostic use.  You
          can specify a sequence of reads and/or writes of byte (b),
          halfword (h), or word (w) width with combinations of -r and
          -w options.  The -c option specifies a repetition count and
          a value for writes that apply to all succeeding writes.  The
          -v option specifies a count and a value for writes that
          apply for all succeeding reads and writes. A final count
          specification indicates the number of times the entire
          preceding pattern should be repeated.  Count defaults to 1
          and value defaults to 0.  A negative count is interpreted as
          infinity.

     EXAMPLE
          >> spin -c 4 -rh 0x2 -c 2 -v 1 -wb 0x4 -c 10

          The example shown above, repeats the two instructions
          shown below, 10 times.

               Read the halfword at address 0x2 four times
               Write 1 to the byte at address 0x4 two times
