Table 14.11
Count source is f1, f2, f4, f8, f32, or TRCCLK input (bits TCK2 to TCK0 in
TRCCR1 register are set to a value from 000b to 101b)
Count source is fOCO40M (bits TCK2 to TCK0 in TRCCR1 register are set
to 110b)
Timer RC is a 16-bit timer with four I/O pins.
Timer RC uses either f1 or fOCO40M as its operation clock. Table 14.11 lists the Timer RC Operation Clock.
Table 14.12 lists the Timer RC I/O Pins, and Figure 14.26 shows a Timer RC Block Diagram.
Timer RC has three modes.
• Timer mode
The following two modes use the output compare function.
• PWM mode
• PWM2 mode
Input capture function, output compare function, and PWM mode settings may be specified independently for
each pin.
In PWM2 mode waveforms are output based on a combination of the counter or the register.

- Output compare function

Condition
The counter value is captured to a register, using an external signal as the trigger.
Matches between the counter and register values are detected. (Pin output state
changes when a match is detected.)
Pulses of a given width are output continuously.
A one-shot waveform or PWM waveform is output following the trigger after
the wait time has elapsed.
