This precinct handles masking off data at the electronics module level.

• Registers:
  

  Group	Register Name	Instances	Multiplicity	Subsections	Type	Width (bits)
  AEM	aem_configuration	1	1	1	mask	12
  TEM	data_masks	16	1	1	mask	16
  TIC	tkr_out_mask	16	1	1	mask	16
  TIC	tkr_layer_enable	16	2	1	mask	18
  TIC	cal_in_mask	16	1	1	mask	16

  
  The two tkr_layer_enable masks are called ``tkr_layer_enable_0'' and ``tkr_layer_enable_1'' and specify the tracker layer enables for layers 0-8 and 9-17 respectively.
