For QMatrix sensors, specifies how many times the switching sequence should be repeated before acquisition begins for each
channel. Each count in the BURSTx field specifies 1 repeat of the switching sequence, so the actual burst length will be BURST.
Before doing a QMatrix acquisition on one X line this register has to be written with the burst values for the current XY pairs. For
each X line this register needs to be programmed with all the Y values. If Y values larger than 3 are used the register has to be
written several times in order to specify all burst lengths.
The Status Register bit MBLREQ is set to 1 when the CAT is waiting for values to be written into this register.
