where the STOP_TRANSMISSION command is implemented: the end bit of the
STOP_TRANSMISSION command from the host is followed, on the data line, by one more
data bit, then an end bit and two Z-bits. The two Z-bits, which correspond to two clock
cycles, are used to switch the bus direction. The received data block is considered
incomplete and will not be programmed.
In the previous stop transmission examples, the host stopped the data transmission during
an active data transfer.

data blocks to be programmed. In the second case, the card starts programming the blocks
upon reception of the STOP_TRANSMISSION command and activates the busy signal.
