Block

Mask

Description

The EnDat 2.2 Master Unpacking block receive the data from the DataIn block and recover all signals needed by the EnDat Master block. Signal concatenation and reordering is performed inside the block.

Parameters

This block has no parameters.

Inputs

DataIn	This port must be connected to one of the DataINi output ports of the DataIn block.
DataInSOF	This prot must be connected to one of the SofINi output ports of the DataIn block.

Outputs

Start

A pulse to start EnDat Transmission

DIN

EnDat Parallel data.

The data available here must contain the data to be transmitted to the EnDat encoder.

Byte	Bit Range	Data Descriptions
4	[29:24]	Mode Command
3	[23:16]	MRS Code / Address / Port Address (depends on the mode command)
2	[15:8]	Parameters / Instructions (depends on the mode command)
1	[7:0]	Parameters / Instructions (depends on the mode command)

Freq_OEM_Value

OEM value to determine transmission frequency. Value lies between 2 and (2^11) -1.

Freq_TST_Value

OEM value to determine the EnDat recovery time "TST". Value lies between 2 and (2^11) -1.

PositionValueWidth

This port provides the width of the position value (max 48 bits).
