According to the Rabbit 6000 User manual, the state of a pin, sometimes called SYSCFG, sometimes called SCFG, affects the operation of the Rabbit 6000 (by potentially overriding the two least-significant bits of MB0CR, and by mapping the internal RAM at /CS0 vs. /CS3). However, the 233 ball variant of the Rabbit 6000 does not have this pin. How does the Rabbit 6000 operate in this case?
Although it’s referred to in the Rabbit 6000 documentation, I don’t think a 233 ball variation of the chip exists. Digi only used the Rabbit 6000 on the RCM66xxW and RCM6700 series boards, and they both used the 292 ball version of the chip.
