16-bit timer/event counter 00 can output a one-shot pulse in synchronization with a software trigger or an external
The basic operation setting procedure is as follows.
<1> Set the count clock by using the PRM00 register.
<2> Set the CRC00 register (see Figures 6-32 and 6-34 for the set value).
<3> Set the TOC00 register (see Figures 6-32 and 6-34 for the set value).
<4> Set any value to the CR000 and CR010 registers (0000H cannot be set).
<5> Set the TMC00 register to start the operation (see Figures 6-32 and 6-34 for the set value).
Remarks 1. For the setting of the TO00 pin, see 6.3 (5) Port mode register 3 (PM3).

Note The case where N < M is described here. When N > M, the output becomes active with the CR000
Cautions 1. Do not set the OSPT00 bit to 1 again while the one-shot pulse is being output. To output the
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 6-32, and by setting bit 6 (OSPT00) of the TOC00 register to 1 by software.
By setting the OSPT00 bit to 1, 16-bit timer/event counter 00 is cleared and started, and its output becomes
active at the count value (N) set in advance to 16-bit timer capture/compare register 010 (CR010). After that,
the output becomes inactive at the count value (M) set in advance to 16-bit timer capture/compare register 000
(CR000)
Even after the one-shot pulse has been output, the TM00 register continues its operation. To stop the TM00
register, the TMC003 and TMC002 bits of the TMC00 register must be cleared to 00.

trigger, do not change the level of the TI000 pin or its alternate-function port pin.
Because the external trigger is valid even in this case, the timer is cleared and started even
at the level of the TI000 pin or its alternate-function port pin, resulting in the output of a
pulse at an undesired timing.
