SPEC_VERS
Defines the MultiMediaCard system specification version supported by the device.
Table 36.
TAAC
Defines the asynchronous part of the data access time.
Table 37.
NSAC
Defines the typical case for the clock dependent factor of the data access time. The unit for
NSAC is 100 clock cycles. Therefore, the maximal value for the clock dependent part of the
data access time is 25.5k clock cycles.
The total access time N
on TAAC and NSAC. It has to be computed by the host for the actual clock rate. The read
access time should be interpreted as a typical delay for the first data bit of a data block.
