counter, the counter rolls over after reaching its maximum count value. If the overflow interrupt is disabled, the
counter holds maximum value upon saturation. Refer to LATCH [addr 046] for a description of 1-second
latched counter operation. The processor must read the Least Significant Byte (LSB) before reading the Most
Significant Byte (MSB) of each multi-byte counter.

If LATCH_CNT [addr 046] is inactive, reading FERR [addr 051] clears the entire FERR[11:0] count value.
