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 ø
SUB
, 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.
