CHAPTER 8 16-BIT TIMER/EVENT COUNTER
(4) 16-bit timer output control register (TOC0)
This register controls the operation of the 16-bit timer/event counter output control circuit. It sets R-S type
flip-flop (LV0) setting/resetting, the active level in PWM mode, inversion enabling/disabling in modes other
than PWM mode, 16-bit timer/event counter timer output enabling/disabling, one-shot pulse output operation
enabling/disabling, and output trigger for a one-shop pulse by software.
TOC0 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets TOC0 value to 00H.
Figure 8-6. 16-Bit Timer Output Control Register Format
Cautions 1. Timer operation must be stopped before setting TOC0 (except OSPT).
2. If LVS0 and LVR0 are read after data is set, they will be 0.
3. OSPT is cleared automatically after data setting, and will therefore be 0 if read.
