Function
Strobe signal indicating that normal space
is accessed and address output on
address bus is enabled.
Strobe signal indicating that normal space
is being read.
Strobe signal indicating that normal space
is written to, and upper half (D15 to D8) of
data bus is enabled or DRAM space write
enable signal.
Strobe signal indicating that normal space
is written to, and lower half (D7 to D0) of
data bus is enabled.
Strobe signal indicating that area 0 is
selected.
Strobe signal indicating that area 1 is
selected
Strobe signal indicating that area 2 is
selected, DRAM row address strobe signal
when area 2 is DRAM space or areas 2 to
5 are set as continuous DRAM space, or
row address strobe signal of the
synchronous DRAM when the
synchronous DRAM interface is selected.
Strobe signal indicating that area 3 is
selected, DRAM row address strobe signal
when area 3 is DRAM space, or column
address strobe signal of the synchronous
DRAM when the synchronous DRAM
interface is selected.
