CHAPTER 16 16-BIT RELOAD TIMER
Counter Operation Mode
Reload mode
When an underflow (0000
continue the count operation. Interrupt request that can be generated at the underflow occurrence can be
also used as an interval timer. The toggle waveform which reverses at every underflow occurrence can be
also output from the TOT0/TOT1/TOT2 terminal.
φ: Machine clock values in parentheses ( ) are when machine clock is in 24 MHz operating.
One-shot mode
When an underflow (0000
The interruption can be generated by the underflow. Short waveform which indicates the count operation
can be also output from the TOT0/TOT1/TOT2 pin during the count operation.
