Read, Write and Erase Time-out Conditions
The times after which a time-out condition for read/write/erase operations occurs are (card independent) 10
times longer than the access/program times for these operations given below. A card shall complete the
command within this time period, or give up and return an error message. If the host does not get a
response within the defined time-out it should assume the card is not going to respond anymore and try to
recover (e.g. reset the card, power cycle, reject, etc.). The typical access and program times are defined as
follows:
Read
The read access time is defined as the sum of the two times given by the CSD parameters TAAC and
NSAC (refer to Table “Card Specific Data (CSD)”). These card parameters define the typical delay
between the end bit
