Format of TI Professional PC timing event table:
<a name=table3244></a>
Offset Size Description (Table 03244)
00h WORD offset of next event table entry
02h BYTE normally unused (FFh)
03h BYTE flags:
bit 7 set if timing event active
bits 6-0 not used by BIOS (0), but could be used by option ROMs
04h WORD timeout count (decremented every 25ms when active)
06h WORD offset of event handler (in segment F400h) to call on event
timeout; the F400h segment allows addressing both system ROMs
and the first 16K of memory (due to the 1M memory wraparound)
