The output then starts with:

|=============================================
|  Extended CSD rev 1.7 (MMC 5.0)
|=============================================
|
|Card Supported Command sets [S_CMD_SET: 0x01]
|HPI Features [HPI_FEATURE: 0x01]: implementation based on CMD13
|Background operations support [BKOPS_SUPPORT: 0x01]
|Extended Security Commands Error [EXT_SECURITY_ERR: 0x00]
|Device life time estimation type B [DEVICE_LIFE_TIME_EST_TYP_B: 01]
| i.e. 0% - 10% device life time used
|Device life time estimation type A [DEVICE_LIFE_TIME_EST_TYP_A: 01]
| i.e. 0% - 10% device life time used
|Pre EOL information [PRE_EOL_INFO: 01]
| i.e. normal
|Device version [DEVICE_VERSION: 38 05]
|Firmware version [FIRMWARE_VERSION: 00 00 00 00 00 00 00 03
