completion of the command e.g., each block has 4 sectors, a request for 8
sectors is issued and an error occurs on the third sector. The Sector Count
Register contains 6 and the address is that of the third sector.
5.1.29
SanDisk does not recommend the use of this command in new designs but it is
supported as a normal Write Sectors command for backward compatibility.
5.1.30
This command writes from 1 to 256 sectors as specified in the Sector Count
Register. A sector count of zero requests 256 sectors. The transfer begins at
the sector specified in the Sector Number Register. When this command is
accepted, the card sets BSY, then sets DRQ and clears BSY, then waits for the
host to fill the sector buffer with the data to be written. No interrupt is
generated to start the first buffer fill operation. The host should not transmit
any data until it has cleared BSY.
For multiple sectors, after the first sector of data is in the buffer, BSY will be
set and DRQ will be cleared. After the next buffer is ready for data, BSY is
cleared, DRQ is set and an interrupt is generated. When the final sector of
data is transferred, BSY is set and DRQ is cleared. This state will be
maintained until the command is completed, at which time BSY is cleared and
an interrupt is generated.
If an error occurs during a write of more than one sector, writing terminates at
the sector in which the error occurs. The Command Block registers contain the
cylinder, head and sector number of the sector where the error occurred. The
host may then read the command block to determine what error occurred, and
on which sector.
