OVR
The OVR bit is the overrun status of the RXCP-50 Performance Monitoring Count Registers.
A logic one in this bit position indicates that a previous transfer (indicated by XFERI being
logic one) has not been acknowledged before the next accumulation interval has occurred and
that the contents of the RXCP-50 Count Registers have been overwritten. OVR is set to logic
zero when this register is read.
XFERI
The XFERI bit indicates that a transfer of RXCP-50 Performance Monitoring Count data has
occurred. A logic one in this bit position indicates that the RXCP-50 Count Registers have
been updated. This update is initiated by writing to one of the RXCP-50 Count Register
locations or to the S/UNI-JET Identification, Master Reset, and Global Monitor Update
Register. XFERI is set to logic zero when this register is read.
