The TPU does not check the value of LINK_CHANNEL_COUNT. If this parameter is NOT >0 and ≤ 8,
results are unpredictible.
MAX_COUNT may be written at any time by the host CPU, but if the value written is ≤ PERIOD_COUNT, a
period or pulse-width accumulation is terminated. If this happens, the number of periods over which the
accumulation is done will not correspond to MAX_COUNT.
