  • We do not know what your "external buffer" is.

    Is it xdata memory internally to the chip?

    Is it xdata memory externally?

    Is it eeprom memory connected using I2C?

    You really have to supply more information if you want help. The information you give - a Winbond controller connected to P0 - is irrelevant.
