S702 information

[dimiras]

Hmm RAM_21, RAM_22 and RAM_23 are related to the CC150.
RAM_21 - "input" I0-I7
RAM_22 - "input" I8-I15
RAM_23 - "output" P2.0 - P2.7
For the configuration I guess... setb RAM_22.1 etc.
Same as X-RAM 0x60?
A040 I find see 1 and FF

How can I support you?

I'm not having much time lately to do some more digging on this.
In my case supposedly:
RAM_20 is A040 read
RAM_21 is A041 read
RAM_22 is A040 write (P2.0-P2.7)

And I think this is the output for the ignition coil drivers:

ignition coil 4	P2.0
ignition coil 3	P2.1
ignition coil 2	P2.2
ignition coil 1	P2.4

I need some help understading what each of those writes on the reset function do.
Do you have any recomendation on some reading material that could help ?
