Ok... So what's the difference between $00FF9E and $00FFEE, assuming native mode? Does $00FF9E get triggered a different way than $00FFEE does?
Have you read the 265’s data sheet ? Page 10 has a cross-reference of native-mode vectors and the corresponding hardware. A similar table for emulation ...

So, everywhere I look, I'm seeing the native mode vectors for the 65816 for IRQ and NMI as $FFEE and $FFEA respectively.

Looking at the w65c265s data sheet, in the table '2.4.2 Native Mode Priority Encoded Interrupt Vector Module', it appears to show IRQ at $FF9E and NMI at $FFBA.

In the table '2 ...

My understanding (of the '134) is that you need to pull BE low before Reset goes low, then keep it low for some time after Reset goes high. Look for a timing value called "tBR" in the data sheet. For the '134 it's defined as a minimum of 35ns at 4Mhz. There is no maximum specified, so maybe there is ...

I saw in another thread a mention about using the BE/RDY and RESB pins to disable the internal ROM on the 65c265.

Can someone explain how this works? I'd like to use the '265, but I'd also like to avoid the crazy boot sequence with $8000 / WDC String.

Thanks!

Just what the title says-

I was looking at the code for symon, and although it does look like 65816 support was started, in that you can select 65816 as the cpu type, looking at files like InstructionTable.java make it look like that support hasn't been completely added yet.

Am I missing ...

Is this the xa you are referencing? Did you try JSL @123456 ? @ render as 24-bit quantity for 65816 (must specify -w
command-line option). This is required to specify any
24-bit quantity!

That's better! Strangely, I had to use 'jsr $@123456' because jsl still returns an syntax error. The output ...

So, I'm trying to get up to speed on the xa assembler, and so far, things are going pretty well.

The weird problem I've run into though is that it is treating 'JSL $123456' as a syntax error. I am passing the '-w' option in the command line.

Any ideas what I'm missing here?

Thanks!
