23 Melody Driver
23.1 Overview
This LSI includes one channel of the melody driver.
To use the melody driver, the secondary function of Port 3 or Port 4 or Port 5 should be set. For the respective
port setting, see Chapter 20, "Port 3", Chapter 21, "Port 4" and Chapter 22, "Port 5". For the clock to be used in
this block, see Chapter 6, "Clock Generation Circuit".
23.1.1 Features
•
In melody output mode, 29 scales (melody audio frequency: 508Hz to 10.922kHz), 63 tone lengths, and
15 tempos are available.
•
In buzzer output mode, 4 output modes, 8 frequencies, and 15 duty levels (7 duty levels when buzzer
frequency
=
4.096kHz) are available.
