This command is similar to the brp_Lg_ReadMIM() command, except that a CRC checksum is calculated over the read Bytes and compared to the CRC checksum given in the CRCAdr parameter.
If these checksums differ, the BRP_Lg_ErrCrc status code will be returned. Depending on the value of the CRCCalc flag given as a parameter in the brp_Lg_Select() command, either 8-bit or 16-bit checksums will be used.
| [in] | protocol | used to execute the command |
| [in] | Adr | Address of data to read. |
| [in] | Len | Number of Bytes to read (0x01 - 0x20). |
| [in] | CRCAdr | Address of CRC checksum for verification of read data. |
| [out] | DataAdr | Address of read data. |
| [out] | Data | Read data. |
| [out] | Data_len | |
| [in] | mempool | is used to store response data. Maybe NULL to use an internal mempool, in this case the data is only available until another command uses the internal mempool |
