Table 14.11
The count source is f1, f2, f4, f8, f32, 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).
Timer RD has 2 16-bit timers (channels 0 and 1). Each channel has 4 I/O pins.
The operation clock of timer RD is f1 or fOCO40M. Table 14.11 lists the Timer RD Operation Clocks.
Figure 14.26 shows a Block Diagram of Timer RD. Timer RD has 5 modes:
The following 4 modes use the output compare function.
In the input capture function, output compare function, and PWM mode, channels 0 and 1 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 1 channel.
In reset synchronous PWM mode, complementary PWM mode, and PWM3 mode, a waveform is output with a
combination of counters and registers in channels 0 and 1.
Tables 14.12 to 14.20 list the Pin Functions of timer RD.
