IBM Processor for Network Resources
12.22: RXCRC Processor State Read/Write Port
Provides read/write access to the internal state of the processor. The internal processor state is externalized
for debug and testing reasons. See the description of RXCRC Processor State Selector on page 345 for
definitions on the addresses.

12.24: RXCRC Checksum Protocol Registers
These registers provide additional protocol bytes for which checksum calculations should be enabled. The
first register allows up to four protocols to be enabled with headers that are similar to UDP and TCP which
use a pseudo-header. The second register allows up to four protocols to be enabled with headers that are
similar to ICMP (no pseudo header). IP, UDP, TCP, V4 ICMP, and V6 ICMP are automatically recognized
and should not be specified again in these registers.
Each byte specifies a different protocol.
