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
Preliminary specification
Specifications in this manual are tentative and subject to change.
Timer RC Operation Clock
Nov 05, 2008
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.
The counter value is captured to a register, using an external signal as the trigger.
