family and 2

for the C5xxx series. W h en the function identi ﬁes an

illegal address, it returns an error message stating that the address

values are out of range.

Note isreadable relies on the memory map optio n in CCS IDE. If

you did not properly deﬁne the memory map for the processor in CC S

IDE,

isreadable does not produce useful results. Refer to your Texas

Instruments’ C ode Composer Studio documen t a t ion f or information on

conﬁguring m emory maps.

Examples When you write scripts to run models in the M ATLAB environment and

CCS IDE, the

isreadable function is very useful. Use isreadable

to check that the channel from which you are reading is conﬁ gured

properly.

cc = ticcs;

rx = cc.rtdx;

% Define read and write channels to the processor linked by cc.

open(rx,'ichannel','r');s

open(rx,'ochannel','w');

enable(rx,'ochannel');

enable(rx,'ichannel');

isreadable(rx,'ochannel')

ans=

isreadable(rx,'ichannel')

ans=

Now that your script knows that it can read from ichannel, it proceeds

to read messages as required.
