Fig 30. EMC block diagram
19.8.1 AHB slave register interface
Figure 30
The functions of the EMC blocks are described in the following sections:
Note: For 32 bit wide chip selects data is transferred to and from dynamic memory in
SDRAM bursts of four. For 16 bit wide chip selects SDRAM bursts of eight are used.
The AHB slave register interface block enables the registers of the EMC to be
programmed. This module also contains most of the registers and performs the majority of
the register address decoding.
To eliminate the possibility of endianness problems, all data transfers to and from the
registers of the EMC must be 32 bits wide.
