The IPAC comprises the basic functionality of the ISAC-S PEB 2086 and of the HSCX-
TE PSB 21525 with additional DMA capability. Therefore the IPAC register set is very
similar to these two devices, which allows for easy adaptation of existing host software.
As shown in figure 98 the B-Channel registers are located in the range from 00h to 73h
whereas the D-Channel specific registers are available from 80h to BAh. As some of the
registers provide similar functionality for B-Channel and D-Channel operation, the
nomenclature indicates to which functional block the register is related to
(e.g. RFIFOB = receive FIFO B-Channel, RFIFOD = receive FIFO D-Channel).
The IPAC specific registers for configuration, interrupt handling, PCM and Auxiliary
interface are located at the upper address range starting at C0h.
