RIRB Size Capability — RO. Hardwired to 0100b indicating that the ICH6 only supports a RIRB size
of 256 RIRB entries (2048B)
Reserved.
RIRB Size — RO. Hardwired to 10b which sets the CORB size to 256 entries (2048B)
Immediate Command Write — R/W . The command to be sent to the codec via the Immediate
Command mechanism is written to this register. The command stored in this register is sent out over
the link during the next available frame after a 1 is written to the ICB bit (HDBAR + 68h: bit 0)
Immediate Response Read (IRR) — RO. This register contains the response received from a codec
resulting from a command sent via the Immediate Command mechanism.
If multiple codecs responded in the same time, there is no guarantee as to which response will be
latched. Therefore, broadcast-type commands must not be issued via the Immediate Command
mechanism.
