29.1.1
This LSI supports an interface based on PCMCIA specifications for physical areas 6. Interfaces
supported are the IC memory card interface and I/O card interface defined in the PCMCIA Rev.
2.1/JEIDA Ver. 4.2 standard. Both the IC memory card interface and I/O card interface are
supported in area 6.
Table 29.1 Features of the PCMCIA Interface
Note:
This LSI can directly access 32- and 64-Mbyte physical areas in a 64-Mbyte memory space and an
I/O space of the PC card (continuous 32/16-Mbyte area mode). This LSI provides a segment bit
(an address bit for the PC card) in the general control register for area 6 to support a common
memory space with full PCMCIA specifications (64 Mbytes).
(1)
Setting 0 (initial value) in bit 3 (P0MMOD) of the general control register enables the continuous
32-Mbyte area mode. In this mode, the attribute memory space and I/O memory space are 32
Mbytes and the common memory space is 64 Mbytes. In the common memory space, set 1 in bit 2
(P0PA25) of the general control register to access an address of more than 32 Mbytes. By this
operation, 1 is output to A25 pin, enabling an address space of more than 32 Mbytes to be
accessed. When an address of 32 Mbytes or less is accessed, set 0 in POPA25. This bit does not
affect access to attribute memory space or I/O memory space.
Figure 29.2 shows the relationship between the memory space of this LSI and the memory and I/O
spaces of the PC card in the continuous 32-Mbyte area mode. Memory space and I/O space are
supported in area 6.
