CHAPTER 8 16-BIT TIMER/EVENT COUNTER
(3) Capture/compare control register 0 (CRC0)
This register controls the operation of the capture/compare registers (CR00, CR01).
CRC0 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets CRC0 value to 04H.

Cautions 1. Timer operation must be stopped before setting CRC0.
2. When clear & start mode on a match between TM0 and CR00 is selected with the 16-
bit timer mode control register, CR00 should not be specified as a capture register.
(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.
