The following bits are used for DRAM bank properties:
PGS2–PGS0—Page Size
DPS1–DPS0—DRAM Port Size
This attribute determines the page size for the DRAM controller (see Table 6-9). The page
size is the smallest DRAM size the user needs to support with page mode capability.
For instance, PGS = 001 (256K) should be used for a 32-bit-wide memory composed of
four 256K
teen 256K
This attribute determines the DRAM bank port size (see Table 6-10). The DRAM controller
asserts the appropriate DSACKx lines according to these bits. If an MC68EC040 access
is performed using this DRAM bank and SPS = 00 or 01, the DRAM controller operates
the same way, but asserts TA instead of DSACK.
The internal DRAM address multiplexer and the page logic sup-
port only a port size of 32 bits or 16 bits. An 8-bit DRAM port size
is not allowed.
The DRAM controller does not support an external DSACKx re-
sponse for a bank on which page mode is used. Also, an exter-
nal DSACK response may not occur before RAS is asserted.
PGS2-PGS0
8 devices, a 16-bit-wide memory composed of two 256K
1 devices. In all cases, the width of the DRAMs is irrelevant.
