signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of Start or Stop condition.
When MPC8640 acts as the I
SCL and SDA are balanced, MPC8640 would not cause unintended generation of Start or Stop condition. Therefore, the 300
ns SDA output delay time is not a concern. If, under some rare condition, the 300 ns SDA output delay time is required for
MPC8640 as transmitter, the following setting is recommended for the FDR bit field of the I2CFDR register to ensure both the
