Interface Description
3.4.1
Decoding for the configuration registers is defined in Table 3-18.
Table 3-18
Attribute Memory Function
Attribute Memory is a space where a CompactFlash Memory Card identification and
configuration information is stored, and is limited to 8-bit wide accesses only at even
addresses. The card configuration registers are also located there.
For the Attribute Memory Read function, signals -REG and -OE must be active and -WE
inactive during the cycle. As in the Main Memory Read functions, the signals -CE1 and -CE2
control the even-byte and odd-byte address, but only the even-byte data is valid during the
Attribute Memory access. Refer to Table 3-19 for signal states and bus validity for the
Attribute Memory function.
