+/* Split ROM data Program for CqREEK SH-3 (Thanks Yamanaka-san) */
+/* Nihon Cygnus Solutions  KASHIWAYA Haruki  '00-4-13 */
+
+/* This program separate ROM data for one ROM socket.
+   The cq board has two ROM sockets, and those bus size can
+   switch to 8bit or 16bit with JP6.
+   If your program is smaller than 32kByte, you can use
+   a 256k bit ROM with 8bit bus mode.
+   However, the board curcuit connection is peculiar.
+   A0 is connected to A14 in 8bit bus mode (See the curcuit diagram),
+   this mean's all odd data are assigned from 0x4000 offset.
+   You must use this program and separate ROM data when you use
+   a 256k bit ROM with 8bit bus mode.
+
+   If your program is bigger than 32kByte, simply, you can use
+   two 256k bit(or bigger) ROM with 16bit bus mode.
+   You do *not* need to use this program.
+   (Details, separate ROM data to odd and even, and write each data to
+   each ROMs, and attach odd's ROM to IC4, even's ROM to IC8.)
