Processor: ADSP-BF534

IDE: VDSP 5.0 Update 6


I want to halt processor when it whill attemp to execute from flash memory resided at addresses 0x20000000-0x20090000. So I set a pair of instruction breakpoints 4-5 in Tools-> Hardware Breakpoints window. Breakpoint's 4 address = 0x20000000, breakpoint's 5 address = 0x20090000. Then I enable range WPIA4 < IA <= WPIA5 and run program. Processor halts at address 0xFFA01114 (which resides in L1 memory) and IDDE outputs the message in console window: "INSTRUCTION breakpoint pair 4-5 triggered at address 0xFFA01114 which lies inside the range 0x20000000 - 0x20090000.". Why???
