The timing diagram for True IDE mode of operation in this section is drawn using the

conventions in the ATA-4 specification, which are different than the conventions used in the

PCMCIA specification and earlier versions of this specification. Signals are shown with their

asserted state as High regardless of whether the signal is actually negative or positive true.

Consequently, the -IORD, the -IOWR and the -IOCS16 signals are shown in the diagram

inverted from their electrical states on the bus.

1. The device addresses consists of −CS0, −CS1, and A2-A0.

2. The Data I/O consist of D15-D0 (16 bit) or D7-D0 (8 bit).

3. −IOCS16 is shown for PIO modes 0, 1 and 2. For other modes, this signal is ignored.
