-Routine Description:
- This is an interface call provided by SNP.
- It does the basic checking on the input parameters and retrieves snp structure
- and then calls the read_nvdata() call which does the actual reading
-
-Arguments:
- this - context pointer
- ReadOrWrite - true for reading and false for writing
- RegOffset - eeprom register relative to the base
- NumBytes - how many bytes to read
- BufferPtr - address of memory to read into
