20. Timer RD
Timer RD has 2 16-bit timers (timer RD0 and timer RD1).
20.1
Table 20.1
The count source is f1, f2, f4, f8, f32, fC2, or TRDCLK input
(bits TCK2 to TCK0 in registers TRDCR0 and TRDCR1 are set to a value from 000b
to 101b).
The count source is fOCO40M
(bits TCK2 to TCK0 in registers TRDCR0 and TRDCR1 are set to 110b).
The count source is fOCO-F
(bits TCK2 to TCK0 in registers TRDCR0 and TRDCR1 are set to 111b).
Timer RDi (i=0 or 1) has 4 I/O pins.
The operation clock of timer RD is f1, fOCO40M or fOCO-F. Table 20.1 lists the Timer RD Operation Clocks.
Figure 20.1 shows a Timer RD Block Diagram, and Table 20.2 lists Pin Configuration of Timer RD.
Timer RD has 5 modes:
• Timer mode
The following 4 modes use the output compare function.
• PWM mode
• Reset synchronous PWM mode
• Complementary PWM mode
• PWM3 mode
In the input capture function, output compare function, and PWM mode, timer RD0 and timer RD1 have the
equivalent functions, and functions or modes can be selected individually for each pin. Also, a combination of
these functions and modes can be used in timer RDi.
In reset synchronous PWM mode, complementary PWM mode, and PWM3 mode, a waveform is output with a
combination of counters and registers in timer RD0 and timer RD1.
