I/O on 2nd C167?
« on: April 15, 2013, 05:23:37 PM »
How are input/outputs on 2nd C167 cpu addressed? I need to find such code to identify a map.
And might also want to use it to control external device.
Anyone who can paste some example code from IDA showing how it's done?

If memory serves, the 2nd C167 is a port expander, but I could be wrong.

I have no logs because I have a boost gauge (makes things easier)

I would rather think that they are connected by the SSC (spi) in Master/Slave mode. Though I've not checked the circuitboard for this.
I need help finding how code/routine is used to address the I/O ports on slave device. I can' remember reading about if the slave C167 have the same internal boot rom or another prepared for SPI com.

Doesn't really answer your question, but have you seen this:

Yes, seen it long before I had the need to identify such code. I Recall Tonys statement that he guessed that it was a watchdog.
It was to some help now when I read it again. I guess that I might get further by finding a few known outputs for which I have known maps.
Thank you
