Carrier Board phyCORE-PXA270
5.3.1 IDE Interface
The PXA270 controller's first PCMCIA interface is used on the
Carrier Board to realize an IDE socket for 2.5" hard drives. PLD U6
provides all the control logic to operate the IDE interface. The 2.0 mm
header connector is located at X20 on the Carrier Board. Mounting
holes for attaching the hard drive are located on the Carrier Board as
well. The hard disk will be attached to the board using spacers on top
of the phyCORE-PXA270 module
(refer to Figure 15 for details) .
