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.

Figure 49. Case 2

When these conditions occur at the same time, the PCM1795 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.

Figure 50. Case 3

When these conditions occur at the same time, the PCM1795 erroneously detects a start or stop condition.
