8.45 Isochronous Receive Context Command Pointer Register
The isochronous receive context command pointer register contains a pointer to the address of the first descriptor
block that the PCI7x21/PCI7x11 controller accesses when software enables an isochronous receive context by
setting bit 15 (run) in the isochronous receive context control register (see Section 8.44) to 1. The n value in the
following register addresses indicates the context number (n = 0, 1, 2, 3).
