  The PEP-II B Factory Low-Level RF System (LLRF) is a fully programmable VXI
based design running under an EPICS control environment. Several RF feedback
loops are used to control longitudinal coupled-bunch modes driven by the
accelerating mode of the RF cavities. This paper updates the performance of the
LLRF system as beam currents reach design levels. Modifications which enhance
the stability, diagnostics, and overall operational performance are described.
Recent data from high current operation is included.
