/* EPROM */
EEPROM = READ_ONLY 0x0400 TO 0x0FEF;

/* RAM */
RAM = READ_WRITE 0x1000 TO 0x3FFF;

/* non-paged FLASHs */
ROM_4000 = READ_ONLY 0x4000 TO 0x7FFF;
ROM_C000 = READ_ONLY 0xC000 TO 0xFEFF;
/* VECTORS = READ_ONLY 0xFF00 TO 0xFFFF; intentionally not defined: used for VECTOR commands below */
//OSVECTORS = READ_ONLY 0xFF8C TO 0xFFFF; /* OSEK interrupt vectors (use your vector.o) */

第一种情况(可以写进去)

ORG $0200
FCB $20

第二种情况(写不进去)

ORG $0400

FCB $20
改成可读可写的也不行.请高人指点.
