6.5
6.5.1
When the H8S/2655 Group is in advanced mode, external space areas 2 to 5 can be designated as
DRAM space, and DRAM interfacing performed. With the DRAM interface, DRAM can be
directly connected to the H8S/2655 Group. A DRAM space of 2, 4, or 8 Mbytes, or 128, 256, or
512 kbytes can be set by means of bits RMTS2 to RMTS0 in BCRH. Burst operation is also
possible, using fast page mode.
6.5.2
Areas 2 to 5 are designated as DRAM space by setting bits RMTS2 to RMTS0 in BCRH. The
relation between the settings of bits RMTS2 to RMTS0 and DRAM space is shown in table 6.5.
Possible DRAM space settings are: one area (area 2), two areas (areas 2 and 3), and four areas
(areas 2 to 5).
