# EnDat {#ENDAT}
[TOC]
## Introduction
EnDat is a bidirectional interface for position encoders. During EnDat operation the EnDat receiver receives position information from the EnDat position encoder.
## Features Supported
- EnDat 2.2 command set
- EnDat 2.1 command set
- Interrupted and continuous clock mode
- Cable length up to 100m @8MHz
- Propagation delay compensation (capable of handling different propagation delay of different
propagation delay of different channels in concurrent multi
channel configuration)
- Automatic estimation of propagation delay
- Receive on-the-fly CRC verification of position, parameters and additional information
- Two modes of operation - host trigger and periodic trigger
- Channel select
- Concurrent multi channel support (up-to 3 encoders with identical part number @ 8MHz maximum)
- "Multi Channel with Encoders of Different Make" using load share mode (Each of PRU, RTU-PRU, and TX-PRU from one PRU-ICSSG slice handles one channel)
- Safety Readiness: Recovery time
## Features Not Supported
In general, peripherals or features not mentioned as part of "Features Supported" section are not
supported in this release, including the below
- Safety
- Clock configuration up to 16MHz
- Independent clocks on multi channel mode.
## SysConfig Features
@VAR_SYSCFG_USAGE_NOTE
SysConfig can be used to configure things mentioned below:
- Selecting the ICSSG instance. (Tested on ICSSG0)
- Selecting the ICSSG0PRUx instance.(Tested on ICSSG0-PRU1)
- Configuring PINMUX.
- Channel selection.
- Selecting Multi Channel with Encoders of Different Make" using load share mode.
