Linked LUT (LINK)
When selecting the LINK input option, the next LUT's direct output is used as the LUT input. In general,
LUT[n+1] is linked to the input of LUT[n]. As an example, LUT1 is the input for LUT0. For the last LUT, the
link wraps so that LUT[0] is linked to the input of LUT[3].

Internal Events Inputs Selection (EVENT)
Asynchronous events from the Event System can be used as input to the LUT. Two event input lines
(EVENTA and EVENTB) are available, and can be selected as LUT input. Before selecting the EVENT
input option by writing to the LUT CONTROL A or B register (CCL.LUTnCTRLB or LUTnCTRLC), the
Event System must be configured.
