Note: * When φ
W
/4 is selected as the TCF input clock in active mode or sleep mode, since the
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, watch mode, or subsleep
mode, φ
W
/4 must be selected as the internal clock. The counter will not operate if any
other internal clock is selected.
