Read latch position or counter value
Name:
Different names are used for these 4 registers depending on their function.
If the comparator returns "TRUE", then the current counter value is latched and copied to these registers. The
calculation of the comparator value used for the latch can be configured in the "Configure calculation of comparator"
register.
