SanDisk Industrial Grade CompactFlash 5000
5.1.31
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.
5.1.32
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 where the error occurs. The Command Block registers contain the
cylinder, head and sector number of the sector in which the error occurred.
The host may then read the command block to determine what error occurred,
and on which sector.
