Symbol
TOC01
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, TM01 is cleared and started.
One-shot pulse output operates correctly in the free-running timer mode or clear & start mode entered by
TI001 pin valid edge input.
The one-shot pulse cannot be output in the clear & start mode entered upon a match between TM01 and
CR001.
The interrupt signal (INTTM011) is generated even when TOC014 = 0.
• LVS01 and LVR01 can be used to set the initial value of the TO01 output level. If the initial value does
• Be sure to set LVS01 and LVR01 when TOE01 = 1.
• LVS01 and LVR01 are trigger bits. By setting these bits to 1, the initial value of the TO01 output level
• The values of LVS01 and LVR01 are always 0 when they are read.
• For how to set LVS01 and LVR01, see 7.5.2 Setting LVS0n and LVR0n.
• The actual TO01/TI011/P06 pin output is determined depending on PM06 and P06, besides TO01
The interrupt signal (INTTM001) is generated even when TOC011 = 0.
