Bits 0 - 7: SDRAM Refresh Time Control (SREFT0 – SREFT7) These 8 bits are used to control the SDRAM
refresh frequency. The refresh rate will be equal to this register value x 8 x 100 Mhz.
Note: This register has a non-zero default value. This should be taken into consideration when initializing
the device.
Note: After changing the value of this register, the user must toggle the GL.SDMODEWS.SDMW bit to
write the new values to the SDRAM.
