timer/counters 5 and 6 are cascaded to function as a 16-bit timer.
value and the timer register (TTREG5, TTREG6) value generates an INTTMR6
interrupt and clears the counter. The counter then continues counting up. The timer
register must be set in the order of lower byte (TTREG5) and upper byte (TTREG6). (It
is also possible to change only the lower or upper byte of the timer register.)

In the 16-bit timer mode, do not change the TTREGj register value while the timer is running. In this
mode, the TTREGj does not have a shift register and the value written to the TTREGj is reflected
immediately after the write operation. Therefore, if the TTREGj value is changed while the timer is
running, unexpected operation may result.
