One-shot pulse output
The value of this bit is always “0” when it is read. Do not set this bit to 1 in a mode other than the one-
shot pulse output mode.
If it is set to 1, TM00 is cleared and started.

One-shot pulse output
One-shot pulse output operates correctly in the free-running timer mode or clear & start mode entered by
TI000 pin valid edge input.
The one-shot pulse cannot be output in the clear & start mode entered upon a match between TM00 and
CR000.

The interrupt signal (INTTM010) is generated even when TOC004 = 0.

Setting prohibited
• LVS00 and LVR00 can be used to set the initial value of the TO00 output level. If the initial value does
not have to be set, leave LVS00 and LVR00 as 00.
• Be sure to set LVS00 and LVR00 when TOE00 = 1.
LVS00, LVR00, and TOE00 being simultaneously set to 1 is prohibited.
• LVS00 and LVR00 are trigger bits. By setting these bits to 1, the initial value of the TO00 output level
can be set. Even if these bits are cleared to 0, TO00 output is not affected.
• The values of LVS00 and LVR00 are always 0 when they are read.
• For how to set LVS00 and LVR00, see 6.5.2 Setting LVS00 and LVR00.
• The actual TO00/TI010/P34/TI52/RTC1HZ/INTP1 pin output is determined depending on PM34 and
P34, besides TO00 output.
