Dear all,
i got pic18f452 to be interfaced with 3.3v i2c device? , my question is ; if i enable the SMBUS bit in the pic18f452. is that mean that the two devices will communicate with 3.3v level? even if the pic is operated with 5v?? and what about the two 10kohm pullups which must be connected to the SDA & SCL OF the pic?

if not what shall i do in order to communicate with the device.

Thanks
