12.1 Overview
12.1.1
• The PWM signals with the periods of approximately 488 ns (HTBCLK=4.096MHz) to 2s (@LSCLK=32.768kHz)
• The output logic of the PWM signal can be switched to the positive or negative logic.
• At the coincidence of PWM signal period, duties, and period & duty, a PWM interrupt (PW0INT) occurs.
• For the PWM clock, a low-speed clock (LSCLK), a high-speed time base clock (HTBCLK), and an external clock
12.1.2
This LSI includes one channel of 16-bit PWM (Pulse Width Modulation).
The PWM output (PWM0) function is assigned to P43(Port 4) and P34(Port 3) as the tertiary function. For the
functions of port 4 and port3, see Chapter 22, “Port 4” and Chapter 2１, “Port 3”.
Figure 12 - 1 shows the configuration of the PWM circuit.
