When øw/4 is selected as the TCC internal 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/ø (s). When the counter is operated in subactive mode or subsleep mode, either
select øw/4 as the internal clock or select an external clock. The counter will not
operate on any other internal clock. If øw/4 is selected as the internal clock for the
counter when øw/8 has been selected as subclock øSUB, the lower 2 bits of the counter
operate on the same cycle, and the operation of the least significant bit is unrelated to
the operation of the counter.
