Description

OD₂₄

VCC

Drive Density Select.

Set to 1 - High data rate.(500Kbps, 1Mbps)

Set to 0 – Low data rate. (250Kbps, 300Kbps)

DENSEL#

OD₂₄

VCC

Motor A On. When set to 0, this pin enables disk drive 0.

MOA#

This is an open drain output.

DRVA#

Drive Select A. When set to 0, this pin enables disk drive A.

This is an open drain output.

Write data. This logic low open drain writes

pre-compensation serial data to the selected FDD. An open

drain output.

WDATA#

DIR#

OD₂₄

VCC

Direction of the head step motor. An open drain output.

Logic 1 = outward motion

Logic 0 = inward motion

STEP#

OD₂₄

VCC

Step output pulses. This active low open drain output

produces a pulse to move the head to another track.

Head select. This open drain output determines which disk

drive head is active.

Logic 0 = side 1

WGATE#

RDATA#

TRK0#

OD₂₄

IN_ts5V

VCC

Write enable. An open drain output.

The read data input signal from the FDD.

Track 0. This Schmitt-triggered input from the disk drive is

active low when the head is positioned over the outermost

track.

INDEX#

IN_ts5V

VCC

This Schmitt-triggered input from the disk drive is active low

when the head is positioned over the beginning of a track

marked by an index hole.

WPT#

IN_ts5V

VCC

Write protected. This active low Schmitt input from the disk

drive indicates that the diskette is write-protected.

Diskette change. This signal is active low at power on and

whenever the diskette is removed.
