Notes:

1.This bit must be cleared by user software to return the M-module to normal operation. The reset bit need only be set to a 1 for a minimum of 1μs to properly reset an M-module.

2.The direction is with respect to the M-module specified. For intermodule triggers, the M-module trigger directions must be set opposite one another for proper operation.
