At recommended operating conditions with OV
SCL clock frequency
Low period of the SCL clock
High period of the SCL clock
Setup time for a repeated START condition
Hold time (repeated) START condition (after this period, the first
clock pulse is generated)
Data setup time
Data input hold time:
Rise time of both SDA and SCL signals
Fall time of both SDA and SCL signals
Data output delay time
Set-up time for STOP condition
Bus free time between a STOP and START condition
Noise margin at the LOW level for each connected device
(including hysteresis)
Parameter
Capacitance for each I/O pin
Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
2. Refer to the MPC8641 Integrated Host Processor Reference Manual for information on the digital filter used.
3. I/O pins will obstruct the SDA and SCL lines if OV
provides the AC timing parameters for the I
