This LSI has an on-chip 16-bit free-running timer (FRT). The FRT operates on the basis of the 16-
bit free-running counter (FRC), and outputs two independent waveforms, and measures the input
pulse width and external clock periods.

TIM8FR1A_010020020700
Selection of four clock sources
One of the three internal clocks ( /2, /8, or /32), or an external clock input can be selected
(enabling use as an external event counter).
Two independent comparators
Two independent waveforms can be output.
Four independent input capture channels
The rising or falling edge can be selected.
Buffer modes can be specified.
Counter clearing
The free-running counters can be cleared on compare-match A.
Seven independent interrupts
Two compare-match interrupts, four input capture interrupts, and one overflow interrupt can be
requested independently.
Special functions provided by automatic addition function
The contents of OCRAR and OCRAF can be added to the contents of OCRA automatically,
enabling a periodic waveform to be generated without software intervention. The contents of
ICRD can be added automatically to the contents of OCRDM 2, enabling input capture
operations in this interval to be restricted.
