5.2 IT8368E Configuration
The ITE IT8368E has been specifically designed to support EPSON LCD/CRT controllers.
Older EPSON Controllers not supporting a direct interface to the Toshiba processor can
utilize the IT8368E MFIO pins to provide the necessary control signals, however when
using the S1D13505 this is not necessary as the Direct Connection described in Section 4,
Direct Connection to the Toshiba TX3912 on page 11 can be used.
The IT8368E must have both Fix Attribute/IO and VGA modes enabled. When both
these modes are enabled a 16M byte portion of the system PC Card attribute a nd IO space
is allocated to address the S1D13505.
When the IT8368E senses that the S1D13505 is being accessed, it does not propagate the
PC Card signals to its PC Card device. This makes S1D13505 accesses transparent to any
PC Card device connected to the same slot.
For mapping details, refer to Section 4.3, Memory Mapping and Aliasing on page 13. For
further information on configuring the IT8368E, refer to the IT8368E PC Card/GPIO
Buffer Chip Specification.
