In my hardware design, the 6503 FS1B function is not used. Will this pin affect the chip when it is suspended?When the 6503 does not use the FS1B pin function, what does the software need to do?Or you don't have to deal with it?
If you don't want to use FS1B function,you can select SBC without FS1B function.
If you select SBC with FS1B function,you have to configure it in related register and pull it up to VPU_FS even if you don't use it!
Thank you for your reply.I have tried to modify the suggestion you gave me, the internal self-check of logic of 6503 has passed, but the MCU code is debugged with the emulator, and the main state machine state is read through the "Mode" register, which is always in Normal Mode. In this working Mode, I cannot initialize the register that must be in INIT Mode.When will this happen? Does this not match "INIT_FS mode is automatically entered after the device is powered on"?What's the problem?
Do you mind to have phone call?
