For a dict in telemetry, the total num of elements is 
RTE_TEL_MAX_DICT_ENTRIES which is 256.
The number of registers may be greater than that.
One option is to seperate the registers in different groups,
each group can be stored in a dict A and can be an entry of another dict B.
RTE_TEL_MAX_DICT_ENTRIES is used so that B has as less as possible 
elements and to make full use of the memory allocated.
