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 TI001 valid edge. In the mode in which clear & start occurs on a match between
the TM01 register and CR001 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 TOC014.
2. If LVS01 and LVR01 are read, 0 is read.
3. OSPT01 is automatically cleared after data is set, so 0 is read.
4. Do not set OSPT01 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
01 (PRM01) is required to write to OSPT01 successively.
6. Do not set LVS01 to 1 before TOE01, and do not set LVS01 and TOE01 to 1 simultaneously.
