(3) 16-bit timer output control register 00 (TOC00)
Note The one-shot pulse output mode operates correctly only in the free-running mode and the mode in which
Cautions 1. Timer operation must be stopped before setting other than TOC004.
This register controls the operation of the 16-bit timer/event counter 00 output controller. It sets/resets the timer
output F/F (LV00), enables/disables output inversion and 16-bit timer/event counter 00 timer output,
enables/disables the one-shot pulse output operation, and sets the one-shot pulse output trigger via software.
TOC00 can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears TOC00 to 00H.
Address: FFBDH

clear & start occurs at the TI000 pin valid edge. In the mode in which clear & start occurs on a match
between the TM00 register and CR000 register, one-shot pulse output is not possible because an overflow
does not occur.
2. LVS00 and LVR00 are 0 when they are read.
3. OSPT00 is automatically cleared after data is set, so 0 is read.
4. Do not set OSPT00 to 1 other than in one-shot pulse output mode.
5. A write interval of two cycles or more of the count clock selected by prescaler mode register
6. Do not set LVS00 to 1 before TOE00, and do not set LVS00 and TOE00 to 1 simultaneously.
7. Do not make settings <1> and <2> below simultaneously. In addition, follow the setting
00 (PRM00) is required to write to OSPT00 successively.
