This is covered in chapter 16.13 of the reference manual for the mpc823e, especially in 16.13.7 "Programming the I2C Controller" Check 16.13.7.5 where they discuss the I2BRG register.
I believe you can run it at any speed upto 115kb/s (you might even get higher but then it is device specific) Hope this helps, K.D. > -----Original Message----- > From: Pergola, Michael [mailto:MichaelPergola at Danfoss.com] > Sent: 14. febr?ar 2002 20:38 > To: linuxppc-embedded at lists.linuxppc.org > Subject: Setting i2c_i2brg > > > > All, > I am using an Embedded Planet MPC823e platform attempting to get I2C > operational.
