SPIN(1prom)         RISC/os 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),
     half word (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 following instructions 10 times:

          Read the half word at address 0x2 four times.
          Write 1 to the byte at address 0x4 two times.
