Operation Theory

4.1.6

FIFO

FIFO is first-in-first-out storage. It is used for storing some preset
position data for comparing. Every time the position is compared,
a new data is retrieve from FIFO into comparator. This mechanism
makes a the continuous triggering function.

4.1.7

PWM & Mapping

PWM is used for adjusting pulse width of trigger. It could also be
switched to a toggle mode. In this mode, the pulse level will
change from low to high or high to low at every time when com-
pared. 

Mapping means four trigger signals are not one-to-one mapping to
four comparators. For example, Comparator 1 could be linked to
trigger channel 2. Comparator 2 could be linked to trigger channel
1 and 4. Comparator 2 and 4 could be linked to channel 3.
