Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

9:0	`RATE`	The ratio of outgoing to incoming throughput. This value determines what portion of a received packet will be stored before its head is transmitted. An optimal setting avoids transmitting bubbles, while adding no delay to packets. The ratio is expressed as 256 / (ratio - 1). The value for rate must be rounded up except when ratio is greater than 4, in which case it must be rounded down. For example, a 4:1 ratio of outgoing to incoming throughput would be indicated by value 0x055. Note that throughput is the product of clock frequency x data bus width. A value of 0x000 causes the rate adapter to store a packet until either the entire packet is received or the buffer becomes full.	`RW`	`0x100`
