Stop Transmission Received after Last Data Block—Card becomes Busy
Erase, Set and Clear Write Protect Timing
The host must first tag the sectors to erase using the tag commands, CMD32-CMD37. The
erase command, CMD38 once issued, will erase all tagged sectors. 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 programming operation.
Table 4-12 defines all timing values.
