Enable generator register map

The shown register map is for the two output variant, for modules with more or less enable signals the corresponding treshold registers should be used at proportionally increasing offsets

Register Name	Register offset	Field name	Field position	Description
ENABLE	0x0	enable	0	Start the enable generator
PERIOD	0x4	period_value	31:0	Period of the output enable events
THRESHOLD_1	0x8	threshold_value	31:0	First enable event treshold
THRESHOLD_2	0xC	threshold_value	31:0	Second enable event treshold
