The erratum NMG_LBC103 is LBIU3 in MPC8548 errata document. Any local bus transaction may fail during LBIU resynchronization process when the clock divider [CLKDIV] is changing. Ensure there is no transaction on the local bus for at least 100 microseconds after changing clock divider LCRR[CLKDIV].
Refer to the erratum LBIU3 of mpc8548.
