_CTRL[7:0]
R/W 5h
Clock divide factor for external DVGA control module.
This factor is used to derive the SPI clock when the device is
acting as a master to control external dvga settings. Should be
programmed such that the output clock is <25 MHz.
dvga_spi_clock = Fs/8/(clk_div_factor_dvga_ctrl+1)
