13. I2C
This section describes the DC and AC electrical characteristics for the I2C interface of the PC8641.
13.1
I2C DC Electrical Characteristics
Table 13-1 provides the DC electrical characteristics for the I
2C interfaces.
Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
2. Refer to the PC8641 PowerQUICC III Integrated Host Processor Reference Manual for information on the digital filter used.
3. I/O pins will obstruct the SDA and SCL lines if OVDD is switched off.
