AW: Queued SCI with Interrupts on MPC555

 
Hallo David,

Two years ago I implemented Queued SCI which musst be implemented with
interrupts. 
The code works well with the MPC555 and MPC565 and we are using it right
now. 

The code is based on the description in the users-guide for MPC555 Cap.
14.9.
In the documentation you will find some flowcharts that helps but... 
it is not so simple to let it run... since (as I remember) you have to set
some
registers in the *.cfg or in the startupcode that are not described in the
chapter.


Bye 
Alfonso Gambuzza
