Pin 17 (CLKM) can be used as a microcontroller master clock source. If the microcontroller
derives the SPI master clock (SCLK) directly from CLKM, the SPI operates in synchronous
mode, otherwise in asynchronous mode.
In synchronous mode, the maximum SCLK frequency is 8 MHz.
In asynchronous mode, the maximum SCLK frequency is limited to 7.5 MHz. The signal at pin
CLKM is not required to derive SCLK and may be disabled to reduce power consumption and
spurious emissions.
