3.8. PCMCIA Power Header (E4)

This header selects the VCC voltage for PCMCIA / CompactFlash cards in the PCMCIA

slot. The SB-X270 does not support automatic voltage selection, so the user is responsible

for setting the correct VCC voltage before inserting the card, by shorting the appropriate

pins on E4. For 5V supply, short pins 1-2 and for 3.3V supply short pints 2-3. VPP is

constant at 5V.

3.9. CardBus Slot (P7)

68-pin PC Card / CardBus slot including card guides.

The SB-X270 implements a simplified CardBus interface, which connects the CardBus

socket directly to the PCI bus of CM-X270. The provided CardBus implementation doesn't

support hot plug, thus the card has to be inserted before powering the system. The

enumeration sequence is performed using on-board glue logic which controls the CB-

FRAME# signal by software.
