Starting a Count with a Down-Counter Value of H'0000: A one-shot pulse will not be output if
the down-count start register (DSTR) is set and the down-counter (DCNT) count started from the
CPU, or the timer connection register (TCNR) is set and DCNT is started by a channel 1 or
channel 2 compare-match, when the DCNT value is H'0000. However, the OSF bit in the timer
status register (TSR) will be set to 1.
The timing in this case is shown in figure 10.61
