TOC00
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 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.
The interrupt signal (INTTM000) is generated even when TOC001 = 0.
• LVS00 and LVR00 can be used to set the initial value of the output level of the TO00 pin. If the initial
• Be sure to set LVS00 and LVR00 when TOE00 = 1.

• The values of LVS00 and LVR00 are always 0 when they are read.

LVS00, LVR00, and TOE00 being simultaneously set to 1 is prohibited.
TO00 pin can be set. Even if these bits are cleared to 0, output of the TO00 pin is not affected.
