Address: FFF9H
Symbol
TOC03
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, TM03 is cleared and started.
One-shot pulse output operates correctly in the free-running timer mode or clear & start mode entered by
TI003 pin valid edge input.
The one-shot pulse cannot be output in the clear & start mode entered upon a match between TM03 and
CR003.
The interrupt signal (INTTM013) is generated even when TOC034 = 0.
• LVS03 and LVR03 can be used to set the initial value of the output level of the TO03 pin. If the initial
• Be sure to set LVS03 and LVR03 when TOE03 = 1.
• LVS03 and LVR03 are trigger bits. By setting these bits to 1, the initial value of the output level of the
• The values of LVS03 and LVR03 are always 0 when they are read.
• For how to set LVS03 and LVR03, see 7.5.2 Setting LVS0n and LVR0n.
The interrupt signal (INTTM003) is generated even when TOC013 = 0.

value does not have to be set, leave LVS03 and LVR03 as 00.
LVS03, LVR03, and TOE03 being simultaneously set to 1 is prohibited.
TO03 pin can be set. Even if these bits are cleared to 0, output of the TO03 pin is not affected.
