Figure 7-8. Format of 16-Bit Timer Output Control Register 00 (TOC00)
Address: FFBDH After reset: 00H R/W
Symbol 7 <6> <5> 4 <3> <2> 1 <0>
TOC00 0 OSPT00 OSPE00 TOC004 LVS00 LVR00 TOC001 TOE00
OSPT00 One-shot pulse output trigger via software
0

1 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.
OSPE00 One-shot pulse output operation control
0 Successive pulse output
1 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.
TOC004 TO00 output control on match between CR010 and TM00
0 Disables inversion operation
1 Enables inversion operation
The interrupt signal (INTTM010) is generated even when TOC004 = 0.
LVS00 LVR00 Setting of TO00 output status
0 0 No change
0 1 Initial value of TO00 output is low level (TO00 output is cleared to 0).
1 0 Initial value of TO00 output is high level (TO00 output is set to 1).
1 1 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, refer to 7.5.2 Setting LVS00 and LVR00.
 The actual TO00/TI010/P01 pin output is determined depending on PM01 and P01, besides TO00
output.
TOC001 TO00 output control on match between CR000 and TM00
0 Disables inversion operation
1 Enables inversion operation
The interrupt signal (INTTM000) is generated even when TOC001 = 0.
TOE00 TO00 output control
0 Disables output (TO00 output fixed to low level)
1 Enables output
