MSCAN Identifier Acceptance Filtering? - ekta...@tatatechnologies.com - Dec 1 6:05:48 2008
Hello Everyone,
I am working on SK-S12XDP512-A board for freescale MC9S12XDP512. I am
facing a problem in setting the Identifier acceptance filters to accept
a specific Identifier.
However I have already gone through a data sheet of MC9S12XDP512. But
still some questions are left:
What data should be written in Acceptance and Mask registers?
Is the data to be written in the Acceptance and Mask registers as same
as specific identifier to be received?
What kind of operations are performed during the whole filtering
process(like ANDing for masking and X-ORing for comparison)?
What is the first stage of filtering process: Masking or Comparison?
Please help me to make the Filtering process crystal clear!!!!!!!!!!
Thank you very much in advance.
Greetings,
Ekta
