Hi,
I used X8148X3874BCYE as CPU in my project, but when the board completes initialization,
generating a low impulse which duration is 100ms on PORn pin results in system halted, through
observation by emulator, I found the reason is the program execution has been in loop, the loop
address is 0x00020a72->0x00020a76->0x00020a8a->0x00020a8e->0x00020aee->0x00020af2->0x00020af6-
>0x00020a72, and the address is in ROM code. I have tested the power and the crystal clock of
DM8148 when in reset, and found it was ok. I don’t know why the execution will get in loop
