1. The receive and transmit ac routine addresses are the only addresses that can address ROM code.
2. For time slots 1—15, the address shown is the first address. Refer to time slot 0 for range information.
3. For channels 1—15, the address shown is the first address. Refer to channel 0 for range information.
4. Per-board refers to a function that is common to all 16 channels in a single chip set.
