MC33774A Driver Document

[mohanagv]

I am unable to understand the InitMap() function and hash table creation in the MC33774A driver code. Is there any documentation available to help understand these concepts?

In which order are the devices added? Also, please check the calculation below.

In the MC33774A driver code, the first device address added to the HashMap is ALL_CHAINS(7) and ALL_DEVICES(63). According to the table above, if we add ALL_CHAINS(7) and ALL_DEVICES(63), the HashMap index will be calculated as:

((7<<8)|63) % 10

This results in an index of 5. Is this calculation correct?

Hi Mohana,

Indeed the calculation you provided is correct, the index for that element in that specific configuration is 5.

As noted in the document, the tables don’t show exactly the position of each element in the table for that specific case, as it does not provide useful information for the user (the allocation for each element is taken care of by designated APIs).

Please use the document as a guideline in order to know what elements you would expect to find in the hash map depending on the configuration used.

Hi Mohana,

Please refer to the attached document describing the Hashmap functionality.

I hope it helps.
