3.1.2 ATA-Disk Module Registers
The following section describes the hardware registers used by the host software to issue commands to the ADM.
These registers are often collectively referred to as the “Task File Registers.”
3.1.2.1 Data Register
This 16-bit register is used to transfer data blocks between the device data buffer and the host. It is also the register
through which sector information is transferred on a Format Track command. Data transfer can be performed in
PIO mode.
3.1.2.2 Error Register (Read Only)
This register contains additional information about the source of an error when an error is indicated in bit 0 of the
Status register. The bits are defined as follows:
D7
D6
D5
D4
D3
D2
D1
D0
BBK
UNC
0
IDNF
0
ABRT
0
AMNF
Bit 7 (BBK) This bit is set when a Bad Block is detected.
Bit 6 (UNC) This bit is set when an Uncorrectable Error is encountered.
Bit 5
This bit is 0.
Bit 4 (IDNF) The requested sector ID is in error or cannot be found.
Bit 3
This bit is 0.
Bit 2 (Abort) This bit is set if the command has been aborted because of an ADM status condition:
(Not Ready, Write Fault, etc.) or when an invalid command has been issued.
Bit 1
This bit is 0.
Bit 0 (AMNF) This bit is set in case of a general error.
