The serial port design is fully static and therefore can operate with tc(SCK) approaching infinity. It is characterized approaching an input frequency
of 0 Hz but tested at a much higher frequency to minimize test time.
If BFSX does not meet this specification, the first bit of the serial data is driven on BDX until BFSX goes low (sampled on falling edge of BCLKX).
After falling edge of the BFSX, data will be shifted out on the BDX pin.
NOTES:
3. Internal clock with external BFSX and vice versa are also allowable. However, BFSX timings to BCLKX always are defined
depending on the source of BFSX, and BCLKX timings always are dependent upon the source of BCLKX.
4. Timings for BCLKX and BFSX are given with polarity bits (BCLKP and BFSP) set to 0.
