Symbol
TOC02
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, TM02 is cleared and started.
One-shot pulse output operates correctly in the free-running timer mode or clear & start mode entered by
TI002 pin valid edge input.
The one-shot pulse cannot be output in the clear & start mode entered upon a match between TM02 and
CR002.
The interrupt signal (INTTM012) is generated even when TOC024 = 0.
• LVS02 and LVR02 can be used to set the initial value of the output level of the TO02 pin. If the initial
• Be sure to set LVS02 and LVR02 when TOE02 = 1.

The interrupt signal (INTTM002) is generated even when TOC012 = 0.
• The values of LVS02 and LVR02 are always 0 when they are read.
• For how to set LVS02 and LVR02, see 7.5.2 Setting LVS0n and LVR0n.

value does not have to be set, leave LVS02 and LVR02 as 00.
LVS02, LVR02, and TOE02 being simultaneously set to 1 is prohibited.
TO02 pin can be set. Even if these bits are cleared to 0, output of the TO02 pin is not affected.
