20.1 Overview
20.1.1
20.1.2
20.1.3
This LSI includes 3-bit Port 2 (P20 to P22) dedicated to output.
Port 2 can output low-speed clock (LSCLK), high-speed output clock (OUTCLK), and melody as a secondary function.
For clock output and melody 0 (MD0) output, see Chapter 6, “Clock Generation Circuit” and Chapter 24, “Melody
Driver”, respectively.
• Allows direct LED drive.
• Allows selection of high-impedance output mode, P-channel open drain output mode, N-channel open drain output
• Allows output of low-speed clock (LSCLK), high-speed clock (OUTCLK), or melody 0 (MD0) as a secondary
