Erase, set and clear write protect timings
The host must first tag the start (CMD32) and end (CMD33) addresses of the range to be
erased. The Erase command (CMD38), once issued, will erase all the selected write blocks.
Similarly, Set and Clear Write Protect commands start a programming operation as well.
The card will signal ‘busy’ (by pulling the DAT line Low) for the duration of the erase or
program operation. The bus transaction timings are the same as those given for the
STOP_TRANSMISSION command in
Re-selecting a busy card
When a busy card in disabled state is reselected, it restores its busy signaling on the data
line. The timing diagram for this command / response / busy transaction is the same as that
for STOP_TRANSMISSION command illustrated in
