hi ,
i am new to this forum aswell as to lpc microcontrller.i'm using lpc1347 to interface an accelerometer (mma8452q) thru i2c interface which is by default in 100khz..trouble is i dont get from datasheet how to set the clock of i2c..i hav a 12MHz crystal oscillator..know how to set sclh and scll..but how to set pclki2c ? i got this formula,
and lpc1347 in standard/ fast mode (by default)

I 2 C bitfrequency =            PCLKI2C
                         ----------------------------------
                              SCLH + SCLL


sorry if i sound too silly, but plzz help..
