usage: rtclock mode clocks base interval onduty

MODE:

            0 - turn clock off
            1 - turn clock on
            2 - set clock parameters
            3 - set clock parameters and turn clock on
            4 - single pulse mode
            8 - set timer output high
           16 - set timer output low
           32 - wait for timer transition (low->high)

   CLOCKS:    - which clock outputs (bitmask 1-31); only 1 bit set if for setup
   BASE:      - clock counting unit in microseconds
   INTERVAL:  - cycle time (high+low durations) in microseconds
   ONTIME:    - duration of high pulse in microseconds
