The SDRAM controller supports accesses to main SDRAM memory from any internal master. It supports standard SDRAM or
double data rate (DDR) SDRAM, but it does not support both at the same time. The SDRAM controller uses SSTL2 and SSTL3
I/O drivers. Both SSTL drive modes are programmable for Class I or Class II drive strength.
9.1
The following timing numbers indicate when data is latched or driven onto the external bus, relative to the memory bus clock,
when operating in SDR mode on write cycles and relative to SDR_DQS on read cycles. The MCF54
a DDR controller that has an SDR mode. Because it is designed to support DDR, a DQS pulse must be supplied to the MCF54
for each data beat of an SDR read. The MCF54
Care must be taken during board design to adhere to the following guidelines and specs with regard to the SDR_DQS signal
and its usage.
