Table 14.11
The count source is f1, f2, f4, f8, f32 and TRDCLK input.
(The TCK2 to TCK0 bits in the TRDCR0 and TRDCR1 registers are set to 000b to
101b.)
The count source is fOCO40M.
(The TCK2 to TCK0 bits in the TRDCR0 and TRDCR1 registers 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 14.27 shows the Block Diagram of Timer RD. Timer RD has 5 modes:
The following 4 modes using 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 every 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 lists the Pin Functions of timer RD.
