A missing ACK typically indicates a wrong address. In this case, address 0x00 is not a valid anyway (it's the General Call address, which almost no device implements). Apparently, you did not configure...

Forum Post: RE: I2C problem with second data burst.

The master must NACK the last received byte. This requires that you set UCTXSTP before reading the last byte from RXBUF (see section 17.3.4.2.2 of the User's Guide).
