I am ussing a MPC8659 microcontroller with a 400MHz platform clock (CCB). I am trying to obtain 100KHz in I2C2 SCL apliying FDR=0X2F (2048) in I2CFDR (400MHz/2/2048 = 97656Hz) yet the SCL line have 190KHz. I am ussing security full rate mode yet I can read in MCP8569ERM.pdf that it doesn't affect in I2C2.
Can you help me please? Does anyone know hot to do it right?
Best regards. Daniel.
