CHAPTER 8 16-BIT TIMER/EVENT COUNTER
(3) 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, output inversion enabling/disabling in modes other
than PWM mode and data output mode.
TOC0 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets TOC0 value to 00H.

Symbol 7 6 5 4 <3> <2> 1 <0> Address When Reset R/W
TOC0 0 0 0 0 LVS0 LVR0 TOC01 TOE0 FF4EH 00H R/W
Cautions 1. Timer operation must be stopped before setting TOC0.
2. If LVS0 and LVR0 are read after data is set, they will be 0.
