Description
Most Significant Word Enable. Must be set on writes to alter SAMPDIV (bits [47:32]).
When cleared, the SAMPDIV field will not be updated. When set, the SAMPDIV field will
be written.
Reserved (Read Only). Reserved for future use.
Sample Divider. Controls the frequency of sampling input data fed into each filter. With a
value of zero, each input is sampled on every PCI clock edge. With a value of 1, each
input is sampled every other clock edge. With a value of 2, it is sampled every third clock
edge, and so on.
Reserved (Read Only). Reserved for future use.
Output Enable 2. Output enable for GNT2# pin.
Output Enable 1. Output enable for REQ1# pin.
Output Enable 0. Output enable for GNT1# pin.
Reserved (Read Only). Reserved for future use.
Output 2. Output for GNT2# pin.
Output 1. Output for REQ1# pin.
Output 0. Output for GNT1# pin.
Reserved (Read Only). Reserved for future use.
Input 2 (Read Only). Filtered input from GNT2# pin.
Input 1 (Read Only). Filtered input from REQ1# pin.
Input 0 (Read Only). Filtered input from GNT1# pin.
