This register contains the numbers of sectors of data requested to be transferred on a read or
write operation between the host and the CompactFlash Storage Card. If the value in this register is zero, a count
of 256 sectors is specified. If the command was successful, this register is zero at command completion. If not
successfully completed, the register contains the number of sectors that need to be transferred in order to
complete the request.
