system clock and internal clock are mutually asynchronous, synchronization is maintained
by a synchronization circuit. This results in a maximum count cycle error of 1/φ (s). When
the counter is operated in subactive mode or subsleep mode, either select φw/4 as the
internal clock or select an external clock. The counter will not operate on any other
internal clock. If φw/4 is selected as the internal clock for the counter when φw/8 has been
selected as subclock φ
the operation of the least significant bit is unrelated to the operation of the counter.
