FUNCTIONAL DESCRIPTION
CL-PS7111
Low-Power System-on-a-Chip
The DRAM controller contains a programmable refresh counter. The refresh rate is controlled using
DRFPR (DRAM Refresh Period register ).
Sixteen- or 32-bit DRAM selection is made based on the value of SYSCON2[2]. Both banks must have
the same width.
The default DRAM width is 32 bits, because SYSCON2 is reset to all zeroes at power up.
