The domain number determines which PI timing/page settings apply to which memory segments. Thus, reads/writes to the cartridge ROM segment use the settings for domain 1. It's possible to configure certain characteristics of the communication protocol: latency, pulse-width, release, and page-size. Domain 1 is set automatically during [[Initial Program Load|IPL2]], by reading the first 4 bytes of the cartridge/device that's connected to the console at boot. Both domains can be configured by software at any time. |
