Notes:
1. The QUICC Engine module needs to run at a frequency higher than or equal to what is listed in this table.
2. ‘F’ is the actual interface operating frequency.
3. The bit rate limit is independent of the data bus width (that is, the same for serial, nibble, or octal interfaces).
4. TDM in high-speed mode for serial data interface.
