7.8 ISDN Register Addresses

To read from or write to indirect register, ﬁrst write an indirect address command

to the command register (CR). One or more data bytes may then be transferred to

or from the selected register through the data register (DR).

Section 7.8.2 lists ISDN register addresses for the 400/500/600/700/800/900

models.

Section 7.8.1 lists ISDN register addresses for the 300 models.

7.8.1 ISDN Register Addresses (300 Models)

The 300 model ISDN register addresses are:
