The motherboard has been tested at 800 x 600 x 16-bit with a static color chart. However,

practical resolution and color depth depend on available bus bandwidth. If a CLCDC in a

daughterboard is the video source, the actual resolution range depends on the daughterboard

CLCDC.

4.5.3 Compact Flash interface

The Compact Flash interface is a custom AMBA AHB-compliant SoC peripheral that is

developed, tested, and licensed by ARM.

The module is an AMBA slave module and connects to the Advanced High-performance Bus

(AHB). The interface supports:

• True IDE Mode, 16-bit.

• IO Mode, data and task file register read and write access only.

Table 4-24 provides information about the CompactFlash interface.

CompactFlash Control Register

The CF_CTRL Register characteristics are:

Purpose The CompactFlash control register

0x0001A300

provides control and status

information for the inserted CF card.

If your daughterboard uses the ARM Legacy memory map the

CompactFlash control register is at SMB CS7 base address +

0x1A000

If your daughterboard uses the ARM Cortex-A Series memory map the

CompactFlash control register is at SMB CS3 base address +

0x1A0000

Note

See the Technical Reference Manual for your daughterboard.

Usage constraints There are no usage constraints.

Configurations Available in all configurations.
