16.5.9.5.4. The STANDBY IMMEDIATE Command
For card devices that do not provide a power savings mode, the STANDBY IMMEDIATE command returns a successful status indication. The host issues a RW_REG command for the ATA command, and the status is retrieved with the SD/SDIO CMD39 or RW_REG command. Only the status field of the ATA task file contains the success status; there is no error status.†
The host controller uses the following settings while sending the RW_REG command for the STANDBY IMMEDIATE ATA command: †
- cmd register setting: data_expected bit set to 0†
- cmdarg register settings: †
- Bit [31] set to 1 †
- Bits [7:2] set to 4 †
- All other bits set to 0 †
- Task file settings: †
- Command field of the ATA task file set to 0xE0†
- Reserved fields of the task file set to 0†
- bytcnt register and block_size field of the blksiz register: set to 16 †
