23 A counter's respective error flag may be cleared by performing a write
24 operation on the respective count value attribute. Although the
25 104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be
26 set, either directly or via the counter's preset attribute. Interrupts
27 are not supported by this driver.
