4.1.4 Encoder Linear Trigger
This function is able to compare counter value by an encoder linear function. Each encoder
supports two linear functions and has four parameters of configuration as below: Start Point,
Repeat Times, Interval and Direction.

Trigger Point (N+1) = Trigger Point N + Interval
(N = Repeat Times, the first trigger condition is start point.)
Trigger output will generate an output signal when Trigger Point equals the current counter
value of a selected encoder channel.
4.1.5 Encoder FIFO Trigger
Encoder FIFO trigger function is used for memory preset position data, and FIFO is first-in and
first-out storage. Furthermore, each encoder supports one encoder FIFO trigger function. After
the preset position is compared, trigger output will generate a output signal. Meanwhile, the
user also can input a new data into FIFO.
4.1.6 Encoder Counter Value Latch
Encoder counter value latch function is used by Latch input signal. The user can set rising or
falling trigger. When the signal is triggered, the encoder counter value will be saved to latch
register. Further, the user can read this value to apply different cases.
The diagram shows the case of position latch.
