(3) 16-bit timer output control register 0n (TOC0n)
154
Cautions 1. Timer operation must be stopped before setting CRC01.
This register controls the operation of the 16-bit timer/event counter 0n output controller. It sets/resets the timer
output F/F (LV0n), enables/disables output inversion and 16-bit timer/event counter 0n timer output,
enables/disables the one-shot pulse output operation, and sets the one-shot pulse output trigger via software.
TOC0n can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears TOC0n to 00H.
