Unknown PM Stuff

This is simply a list of things I need to figure out.

• The precise timing of a video frame. <- Hmm, how precise?
• The number of cycles each value of PRC_CNT takes
• Which\if timers sleep while the system is suspended
• Check to see which IRQs are masked by the IRQ Enable and IRQ Branch flags
• Determine the approximate amount of time sprite draw, map draw, and frame copy take (maybe min \ max \ avg)
• Determine when the PRC stages fire (relative to PRC_CNT)
• Check undocument Minx instruction behavior Done

.. to be continued ..
