3.1.4 True IDE Mode Addressing
When the CompactFlash card is configured in the True IDE mode, the I/O decoding is as follows:
3.1.5 CF-ATA Registers
The following section describes the hardware registers used by the host software to issue commands to the Com-
pactFlash device. These registers are often collectively referred to as the “task file.”
Note: In accordance with the PCMCIA specification: each of the registers below which is located at an odd offset
address may be accessed at its normal address and also the corresponding even address (normal address
-1) using data bus lines (D15-D8) when -CE1 is high and -CE2 is low unless -IOIS16 is high (not asserted)
and an I/O cycle is being performed.
3.1.5.1 Data Register (Address - 1F0H[170H];Offset 0,8,9)
The Data register is a 16 bit register, and it is used to transfer data blocks between the CompactFlash card data
buffer and the Host. This register overlaps the Error register. The table below describes the combinations of data
register access and is provided to assist in understanding the overlapped Data register and Error/Feature register
rather than to attempt to define general PCMCIA word and byte access modes and operations. See the PCMCIA
PC Card Standard Release 2.0 for definitions of the Card Accessing Modes for I/O and Memory cycles.
Note: Because of the overlapped registers, access to the 1F1H, 171H or offset 1 are not defined for word (-CE2=0
and -CE1=0) operations. These accesses are treated as accesses to the Word Data register. The duplicated
registers at offsets 8, 9 and DH have no restrictions on the operations that can be performed by the socket.
