CF-ATA registers
45/82
8.2.4
Bit 4 (IDNF)
This bit is set if the requested sector ID is in error or cannot be found.
8.2.5
Bit 3
This bit is ‘0’.
8.2.6
Bit 2 (abort)
This bit is set if the command has been aborted because of a card status condition (Not
Ready, Write Fault, etc.) or when an invalid command has been issued.
8.2.7
Bit 1
This bit is ‘0’.
8.2.8
Bit 0 (AMNF)
This bit is set when there is a general error.
8.3
Feature register (address 1F1h [171h]; offset 1, 0Dh write
only)
This write-only register provides information on features that the host can utilize. It is
accessed on data bits D15 to D8 during a write operation to offset 0 with –CE2 Low and –
CE1 High.
8.4
Sector Count register (address 1F2h [172h]; offset 2)
This register contains the number of sectors of data to be transferred on a read or write
operation between the host and 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 completion. If
not successfully completed, the register contains the number of sectors that need to be
transferred in order to complete the request. The default value is 01h.
8.5
Sector Number (LBA 7-0) register (address 1F3h [173h];
offset 3)
This register contains the starting sector number or bits 7 to 0 of the logical block address
(LBA), for any data access for the subsequent sector transfer command.
