2.1.2.3 IDE
interface
The E-IDE (Enhanced IDE) interface circuit for hard disc is incorporated in the FW82371EB.
The E-IDE is provided with two interfaces, Primary and Secondary.
Since the E-IDE interface is intended to be exclusively used for AT-compatible machines and a control circuit is accommodated
on the HDD side, it is connected with the parallel data bus with the use of control signals.
With an I/O access action from the CPU side, the E-IDE interface performs direct access to the register group in the drive in
order to control this drive. The primary side drive is selected by PDA0
~
PDA2 and the chip select PDCS1# and PDCS3#1. The
read and write functions are selected by the use of the PDIOW# and PDIOR# signals.
For interrupt, IRQ14 is used on the primary side and IRQ15 is used on the secondary side.
