40.2.13 SD Error Status Register 1 (SDERSTS1)
Note 1. Command other than CMD12 or CMD52 which are automatically issued to stop data transfer.
Note 2. CMD12 or CMD52 which are automatically issued to stop data transfer.
The SDERSTS1 register indicates the CRC status token, CRC error, end bit error, and command error.
