Case 2:
1.
t(SCK) > 120 ns
2.
t(S−HD) or t(RS−HD) < t(SCK) × 5
3.
Spike noise exists on both SCL and SDA during the hold time.
SCL
SDA
Noise
When these conditions occur at the same time, the PCM1792 fails to detect a start condition.
Case 3:
1.
t(SCK) < 50 ns
2.
t(SP) > t(SCK)
3.
Spike noise exists on SCL just after SCL goes LOW.
4.
Spike noise exists on SDA just before SCL goes LOW.
SCL
SDA
Noise
When these conditions occur at the same time, the PCM1792 erroneously detects a start or stop condition.
