19. Timer RC
Timer RC is a 16-bit timer with four I/O pins.
19.1
Table 19.1
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)
Count source is fOCO-F (bits TCK2 to TCK0 in TRCCR1 register are set to
111b)
Timer RC uses either f1, fOCO40M or fOCO-F as its operation clock. Table 19.1 lists the Timer RC Operation
Clock.
Table 19.2 lists the Pin Configuration of Timer RC, and Figure 19.1 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.
- Input capture function
- Output compare function
Overview
Timer RC Operation Clock
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.
