The assignment of cam pairs to onboard outputs

is controlled by machine data:

MD10480 SW_CAM_TIMER_FASTOUT_MASK

(screen form for output of cam signals via timer interrupts to NCU).

In addition, the general machine data below must be set to explicitly select the mode of

MD10485 SW_CAM_MODE Bit0=1

This function runs independently of the assignment in machine data:

MD10470 SW_CAM_ASSIGN_FASTOUT_1 or

MD10471 SW_CAM_ASSIGN_FASTOUT_2 or

MD10472 SW_CAM_ASSIGN_FASTOUT_3 or

MD10473 SW_CAM_ASSIGN_FASTOUT_4.

The onboard byte may not be used more than once at any one time.
