Note The one-shot pulse output mode operates correctly only in the free-running mode and the mode in which
Cautions 1. Timer operation must be stopped before setting other than TOC004.

clear & start occurs at the TI000 pin valid edge. In the mode in which clear & start occurs on a match
between the TM00 register and CR000 register, one-shot pulse output is not possible because an overflow
does not occur.
2. If LVS00 and LVR00 are read, 0 is read.
3. OSPT00 is automatically cleared after data is set, so 0 is read.
4. Do not set OSPT00 to 1 other than in one-shot pulse output mode.
5. A write interval of two cycles or more of the count clock selected by prescaler mode register
6. Do not set LVS00 to 1 before TOE00, and do not set LVS00 and TOE00 to 1 simultaneously.
7. Perform <1> and <2> below in the following order, not at the same time.
00 (PRM00) is required to write to OSPT00 successively.
