Note

For pin mapping see Table 3-1:, “Generic MPU Host Bus Interface Pin Mapping”.

The Generic MPU host interface control signals of the S1D13504 are asynchronous with respect to the S1D13504 bus clock. This gives the system designer full flexibility in choosing the appropriate source (or sources) for CLKI and BUSCLK. Deciding whether both clocks should be the same and whether to use DCLKOUT (divided) as the clock source, should be based on the desired:

pixel and frame rates.

power budget.

part count.

maximum S1D13504 clock frequencies.

The S1D13504 also has internal clock dividers providing additional flexibility.

5.3 IT8368E Configuration

The IT8368E provides eleven multi-function IO pins (MFIO). The IT8368E (or the first in a two-IT8368E implementation) must have both “Fix Attribute/IO” and “VGA” modes on. When both these modes are enabled, the MFIO pins provide control signals needed by the S1D13504 host bus interface, and a 16M byte portion of the system PC Card attribute and IO space is allocated to address the S1D13504. When accessing the S1D13504 the associated card-side signals are disabled in order to avoid any conflicts.

Note

When a second IT8368E is used, it should not be set in VGA mode.

For mapping details, refer to Section 5.4, ‘Memory Mapping and Aliasing”

For further information on configuring the IT8368E, refer to the IT8368E PC Card/GPIO Buffer Chip Specification.
