Note:
1. The QE 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 (i.e. the same for serial, nibble, or octal
interfaces).
4. TDM in high-speed mode for serial data interface.
