(12) Reading of 16-bit timer counter 00 (TM00)
TM00 can be read without stopping the actual counter, because the count values captured to the buffer are fixed
when it is read. The buffer, however, may not be updated when it is read immediately before the counter counts up,
because the buffer is updated at the timing the counter counts up.
