## :wrench: AXI-LITE INTERFACE

For FIR engine setting(follow belows address).

| **Address** | **name** | ... |
|---------- |---------- |---------- |
|0X00 | FIR state |[0]:(Start)/ [1]:Done / [2]:Iddle
|0X10 |Data Length|Number of Data(Input X)
|0X14 |Tap numbers|Number of Tap Parameter(Coefficient h)
|0X80-0X7F |Tap Parameter|Coefficient h

:small_blue_diamond: Reading waveform :

:::warning
Can't read Tap parameter (0X80-0X7F) when FIR engine is running, but Configuration read is OK (0X00-0X14).
:::

:::warning
Can't change these sets when FIR engine is running .
