Note The one-shot pulse output mode operates correctly only in the free-running mode and the mode in which
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.
Cautions 1. Timer operation must be stopped before setting other than TOC004.
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
00 (PRM00) is required to write to OSPT00 successively.
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.
<1> Set TOC001, TOC004, TOE00, OSPE00: Timer output operation setting
<2> Set LVS00, LVR00:
Timer output F/F setting
