Note 1: PLL input requirements: 4 MHz  FPLLIN  5 MHz (use PLL prescaler to reduce Fosc). This parameter is
characterized, but tested at 10 MHz only at manufacturing.
2: This parameter is characterized, but not tested in manufacturing.

2: The minimum clock period for SCKx is 40 ns. Therefore, the clock generated in Master mode must not
violate this specification.
