It is possible to monitor when correction pulses are applied. The correction interrupt
enable mode (bit CIE) will generate a
applied. In the case where multiple correction pulses are applied, a
pulse will be generated and repeated every
Correction is applied to the 1 Hz clock. Any timer or clock output using a frequency of 1 Hz
or below will also be affected by the correction pulses.
