The Data Register is a 16-bit read/write register used for transferring data
between the CF Card and the host. This register can be accessed in word mode
and byte mode.
The Error Register is a read-only register that is used for analyzing an error. This
register is valid when the BSY bit in the Status register and Alternate Status
register are set to ―0‖ (Ready). Diagnostic Codes are returned in the Error
Register after a Execute Drive Diagnostic command (code 90h). Extended Error
Codes returned in the Error Register after a Request Sense command (code
03h).
This register contains the numbers of sectors of data requested to be transferred
on a read or write operation between the host and the CF Card. If the value in the
register is 0, a count of 256 sectors is indicated.
When the LBA bit in the Drive/Head register is 0, this register contains the
starting sector number for any media access. When the LBA bit is set to 1, this
register contains bits 7:0 of the LBA for any media access.
In CHS mode (LBA=0), this register contains the low-order bits of the starting
cylinder address. In LBA mode, it contains bits 15:8 of the LBA.
In CHS mode (LBA=0), this register contains the high-order bits of the starting
cylinder address. In LBA mode, it contains bits 23:16 of the LBA.
This register selects the CF Card address translation (CHS or LBA) and provides
head address (CHS) or high-order address bits 27:24 for LBA.
This read-only register indicates status of a command execution. When the BSY
bit is ―0‖, the other bits are valid; when the BSY bit is ―1‖, the other bits are not
valid. When the register is read, the interrupt pin, is cleared.
This register is the same as the Status register, except that is not negated when
the register is read.
This write-only register is used for controlling the interrupt request and issuing an
ATA soft reset to the CF Card.
This read-only register is used for confirming the CF Card’s status. This register is
provided for compatibility with the AT disk drive interface and it is not
recommended that this register be mapped into the host’s I/O space because of
potential conflicts on bit 7.
This write-only register is used for writing the command that executes the CF
Card’s operation. The command code is written in the command register after its
parameters are written in the Task File during the CF Card ready state.
