MCF51QE/ I2C question

mlun — Tue, 09 Feb 2010 21:11:35 GMT

Hello,

I am going to use the IIC-module on a MCF51QE32 and I was reading the in the reference manual page 267, about generating a start signal:

Master Mode Select. The MST bit changes from a 0 to a 1 when a start signal is generated on the bus and master

mode is selected.

I dont understand this.. Shouldnt it be something like this:

Master Mode Select. When the MST bit changes from a 0 to a 1 a start signal is generated on the bus and master mode is selected.

Regards

Magnus

Another question..

When I simulate using IIC2-module, I get the message "IIC2 module not implemented".

Device is MCF51QE32 and CW V6.3. As far as I can understand the IIC2-module should be implemented in the device, but can the simulator only handle one IIC-module?

I replaced IIC2 with IIC1 and still get the message IIC1-module not implemented, so I guess this is just a simulator problem..
