7-3. Host interface

TC6374AF supports as a host interface the PC Card (Memory, ATA) interface. In PC Card ATA interface, it

supports 4 types of I/O mode(Memory Mapped I/O, Independent I/O, Primary and Secondary). Furthermore,

PC Card interface has a memory space called attribute memory allowing the software to configure

TC6374AF(“*” indicated in the table shown later means “Don’t Care”.).

7-4. PC Card interface

7-4-1. Attribute Memory space

Attribute memory consists of CIS(Card Information Structure) with which a host recognizes the function type

connected with TC6374AF and FCR (Function Configuration Register) for configuration. Attribute memory

can be accessed of course in the memory interface state, and additionally, even after set to the I/O interface.

Access methods and addresses of register in the attribute memory are listed below.

7-4-1-1. Attribute Memory read operation

During the Attribute Memory Read Cycle, set #WE to inactive “1”, and #REG and #OE to active “0”. #CE2,

#CE1 and A0 are controlled at odd/even addresses, though Attribute Memory access is enabled only at even

address data.
