What's the difference between the MC13213 with data code 0725 and 0825(6) ?

What`s the difference between devices with date code 0726(CTAA0726) and 0825(6)(CTBA0825,CTBB0826)?  Our program (based on SMAC) work fine on 0726 and not fully functional on 0825(6) - no RX/TX (no signal out/in - interrupts ok). Current errata only for 0920 and later. Any errata/info on 0825(6)?

Problem solved - our external crystal oscillator has poor accuracy. Thanks to freescale technical support.
