Event Counter
13.8 Event Counter Data Registers
These read-only registers are the basis of all event counter operations. While the gate signal is low, the
value of the most recent event count will remain in the event counter data registers. After the event
counter interrupt, the result of the event count can be read. If the event counter data registers are read
while the gate signal is high, an incorrect value may result.
