I
Subject to general operating conditions for V
The STM8L I
protocol described in the following table with the restriction mentioned below:
Refer to I/O port characteristics for more details on the input/output alternate function
characteristics (SDA and SCL).
Table 44.
1. f
2. Data based on standard I
For speeds around 200 kHz, the achieved speed can have a5% tolerance
For other speed ranges, the achieved speed can have a 2% tolerance
The above variations depend on the accuracy of the external components used.
