These bits should be set to their default values for proper operation

XFERI

The XFERI bit indicates that a transfer of Transmit Cell Count data has occurred. A logic one

in this bit position indicates that the Transmit Cell Count Registers have been updated. This

update is initiated by writing to one of the Transmit Cell 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.

OVR

The OVR bit is the overrun status of the Transmit Cell 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

Transmit Cell Count Registers have been overwritten. OVR is set to logic zero when this

XFERE

The XFERE bit enables the generation of an interrupt when an accumulation interval is

completed and new values are stored in the Transmit Cell Count Registers. When XFERE is

set to logic one, the interrupt is enabled.
