Variable Clock Pattern
The value in this field is the frequency patterns of the SPI clock. If the bit pattern of
VARCLK is ‘0’, the output frequency of SPICLK is according the value of DIVIDER. If
the bit patterns of VARCLK are ‘1’, the output frequency of SPICLK is according the
value of DIVIDER2. Refer to register SPI_DIVIDER.
