READ_BL_LEN
The maximum read data block length is computed as 2
READ_BL_LEN
. The maximum block length might therefore be in
the range 512...2048 bytes (see Chapter 4.11 for details). Note that in SD Memory Card the WRITE_BL_LEN is always
equal to READ_BL_LEN
•
READ_BL_PARTIAL (always = 1 in SD Memory Card)
Partial Block Read is always allowed in SD Memory Card. It means that smaller blocks can be used as well. The
minimum block size will be one byte.
•
WRITE_BLK_MISALIGN

memory device. The size of the memory block is defined in WRITE_BL_LEN.
WRITE_BLK_MISALIGN
=0 signals that crossing physical block boundaries is invalid.
WRITE_BLK_MISALIGN
=1 signals that crossing physical block boundaries is allowed.
