Detailed Description

Calorimeter data PISO for process FPGA.

This is module takes the calorimeter data in at 224 bits per MGT channel, then generates 7 x 32-bit data together with 7 x 1b valid and 1b synch signals

It also changes the 32-b input data to 36-bit ouput data by adding the 4-bit error flags to the 36-bit word. The 4 bit error flags are used when constructing an RAW Readout Frame (event) which are: zero + input_crc + input_disparity + not_in_table
