■ Sample Program for 16-bit Output Compare
●
Processing
A output compare match interrupt is generated when the count value of 16-bit free-run timer is matched
with output compare 0.
• The 16-bit free-run timer is used in up-count mode.
2
• EI OS is not used.
• 16 MHz is used for the machine clock, and 62.5 ns is used for the count clock of 16-bit free-run timer.
