      <p>Hmm, maybe clock driver code has been changed during the years
        to read or write some register bits that are illegal on the
        3-chip ERC32. This would cause a trap to error mode and most
        likely a watchdog reset. I quickly looked through the ERC32
        clock driver code but could not see anything obvious. It could
        also be an ERC32 interrupt driver issue - enabling interrupts
        seems to trigger the problem. I will try to run ticker on an old
        version of sis that did some more checks for the 3-chip version

    <p>One thing to look out for is the watchdog timeout. RTEMS does not
      touch the watchdog, so if the board hardware or firmware does not
      disable the watchdog, program that runs longer than a few seconds
      will be reset by the watchdog. This would apply to ticker ...</p>
