I2C bus question on the MPC8544 (acting as a slave).

I am trying to read data from the I2C bus with the MPC8544 acting as a slave.

I write 0x7e to the I2CADR (offset 0x000), 0x55 to the I2CDR (offset 0x010), and 0x81 to the I2CCR (offset 0x008).

If this is not the proper pseudo-assembly code sequence to set up the MPC8544 as a slave with addr 0x7e, what am I missing?


When I try a read using the SDA (I2C bus), I do not get out any data.
