VRQ Statistics
• VRQ Receive Statistics

EMAC collects basic statistics on an individual generic VRQ basis. Though the accumulation mechanism
remains the same, i.e., these registers are Clear-On-Read, these statistic registers are independent of the
aggregated EMAC statistics registers for LAN and APE (see “VRQ Statistics” on page 454).
