I need c example code for DMA chaining in TS203.
Looks like when I replied earlier the first response was empty and the second one had the attachments. Not sure on whether you were able to access the same. I have added the example code for Link port DMA chaining here. Can you refer this code and let me know if you have any additional questions?
There is no file attached in this email .
Kindly clear the following issue I am having while defining TCB for
In Quad word transfer mode , how we will interpret the the word count
parameter, either it define the total numbers of words to be transferred or
the total numbers of quad words to be transferred?.
My task is to transfer 1024K words on linkport using DMA.
In TS203 Linkport DMA ,upper 16 bits of TCB's DX register hold the word
count to be transfer and lower 16 hold the modifier.
For quad word transfer mode, modifier will be 4 but what will be the word
Since word count is 16 bit so max value to be store is 2^16= 65536.
My confusion is ,in quad word transfer mode the value stored in word count
parameter will be the total numbers of words to be transferred or total
numbers of quad words transfer?
Means if in quad word transfer mode I set word count value to 65536
then what will happen either DMA will transfer 65536 word or 65536 quad
word that will be equal to 65536*4=262144 word?

I am not sure on what is wrong here. I can see the example codes in the link. Can you try your setup and see whether you are able to get the attachments? Otherwise please contact the private support and we will share the codes again.
