Notes:
1. The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state)
for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I
2C timing
(I2) with respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the
high (H) state or setup time. Also, tI2SXKL symbolizes I
2C timing (I2) for the time that the data with respect to the start
condition (S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH
symbolizes I2C timing (I2) for the time that the data with respect to the stop condition (P) reaching the valid state (V) relative
to the tI2C clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used
with the appropriate letter: R (rise) or F (fall).
2. MPC8541E provides a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
3. The maximum tI2DVKH has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal.
4. CB = capacitance of one bus line in pF.
5. Guaranteed by design.
