Test Method
C (1) While monitoring #17 (HD OUT), change SA 04H data from 80H to 88H, and measure #17 pin waveform
phase amount ∆HP0−.
(2) While monitoring #17 (HD OUT), change SA 04H data from 88H to 8FH, and measure #17 pin waveform
phase amount ∆HP0+.
(3) Set SA 00H data to 82H. While monitoring #17 (HD OUT), change SA 04H data from 80H to 88H, and
measure #17 pin waveform phase amount ∆HP1−.
(4) While monitoring #17 (HD OUT), change SA 04H data from 88H to 8FH, and measure #17 pin waveform
phase amount ∆HP1+.
(5) Set SA 00H data to 84H. While monitoring #17 (HD OUT), change SA 04H data from 80H to 88H, and
measure #17 pin waveform phase amount ∆HP2−.
(6) While monitoring #17 (HD OUT), change SA 04H data from 88H to 8FH, and measure #17 pin waveform
phase amount ∆HP2+.
(7) Set SA 00H data to 86H. While monitoring #17 (HD OUT), change SA 04H data from 80H to 88H, and
measure #17 pin waveform phase amount ∆HP3−.
(8) While monitoring #17 (HD OUT), change SA 04H data from 88H to 8FH, and measure #17 pin waveform
phase amount ∆HP3+.
