10. PWM
10.1 Overview
10.1.1 Features
10.1.2 Configuration
This LSI includes one channel of 16-bit PWM (Pulse Width Modulation).
The PWM output (PWM0) is assigned to the tertiary function of the P43 (Port 4) or the secondary function of the P24
(Port 2). For the functions of Port 4 and Port 2, see Chapter 17, “Port 4” and Chapter 15, “Port 2”.
• Capable of generating and externally outputting a PWM signal at a cycle ranging from 2000ns (@HTBCLK =
• 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
are available.
(*) For HSCLK 2MHz, the cycle ranges from 500ns (@HTBCLK=2MHz) to 2s (@LSCLK=32.768kHz).
Figure 10 - 1 shows the configuration of the PWM circuit.
