Notes 1: This is valid when the high-speed running is selected.
2: When the clock source select bit = 1, f(XIN) is 20 MHz or less at the high-speed running, and f(XIN) is 12.5 MHz or less at the low-speed running.

Note: The test conditions are as follows:
• One D-A converter is used.
• The D-A register value of the unused D-A converter is “0016.”
• The reference power supply input current of the ladder resistance of the A-D converter is excluded.
