SDRAM (bus) clock (same frequency as CPU clock). This dedicated output reduces setup and
hold time uncertainty due to process and temperature variations. SDCLK is disabled for
SDRAM power-down mode.
SDRAM clock enable
SDRAM chip select/CS7. The SDRAM is assigned to CS7 (SDRAMCS) of the device chip
select module.
