The dead bus cycles are predictable. In the data sheet (you might have to look at the '816 data sheet to get the info on what happens in every cycle of every addressing mode), it shows dead bus cycles as "IO" for "internal operation." In the case of reset, the 65c02 reset process that it carries out after the RST\ line comes up takes 7 clocks, and it fetches the reset vector in numbers 6 and 7.
http://WilsonMinesCo.com/ lots of 6502 resources

What's an additional VIA among friends, anyhow?

Hi Banedon.

I figured out why it wasn't working on 115200, the serial window has a dropdown option box where you choose which rate.
Didn't know I had to set the arduino project and the serial window :oops: ....
I find out things this way all the time with electronics :).
Sounds like you're doing well with your project. As Garth says; That boot sequence sounds normal.
I've just booted up my latest creation and it gave:

Code: Select all

Address bus  Data bus  Notes
-----------  --------  -----
$FFFF        $EF        
$FA43        $00        
$01FF        $5F        access the stack/stack initialisation
$01FE        $AF        access the stack/stack initialisation
$01FD        $FD        access the stack/stack initialisation
$FFFC        $00        load LSB of reset vector
$FFFD        $F0        load MSB of reset vector
$F000                   jump to reset vector & start of my main code at $F000

Which CPU are you using? Rockwell 65C02, WDC 65C02, or WDC 65C816?

Mine is a WDC W65C02S. I think beholder's one is, too.
