Remark N < M
A one-shot pulse can be output from the TO00 pin by setting 16-bit timer mode control register 00 (TMC00),
capture/compare control register 00 (CRC00), and 16-bit timer output control register 00 (TOC00) as shown in
Figure 6-34, and by using the valid edge of the TI000 pin as an external trigger.
The valid edge of the TI000 pin is specified by bits 4 and 5 (ES000, ES010) of prescaler mode register 00
(PRM00). The rising, falling, or both the rising and falling edges can be specified.
When the valid edge of the TI000 pin is detected, the 16-bit timer/event counter is cleared and started, and the
output becomes active at the count value set in advance to 16-bit timer capture/compare register 010
(CR010).

Note The case where N < M is described here. When N > M, the output becomes active with the CR000
