8.14
This timing is based on the SL11R Processor Clock (PCLK) = (2/3) of RCLK = 32MHz (see the register 0xC006 for information
about PCLK).
Note: This timing is base on EDO DRAM timing 16Mx16 devices. When the SL11R processor is set up for a higher speed (i.e.
48MHz clock), then the faster parts (i.e. 50ns or 60ns) should be used.
