DRVA#

OD24

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

drive A. This is an open drain output.

10

WDATA#

OD24

VCC Write data. This logic low open drain writes

pre-compensation serial data to the selected FDD. An

open drain output.

11

DIR#

OD24

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

Logic 1 = outward motion

Logic 0 = inward motion

12

STEP#

OD24

VCC Step output pulses. This active low open drain output

produces a pulse to move the head to another track.

13

HDSEL#

OD24

VCC Head select. This open drain output determines which

disk drive head is active.

Logic 1 = side 0

Logic 0 = side 1

14

WGATE#

OD24

VCC Write enable. An open drain output.

15

RDATA#

INts5v

VCC The read data input signal from the FDD.

16

TRK0#

INts5v

VCC Track 0. This Schmitt-triggered input from the disk

drive is active low when the head is positioned over

the outermost track.

17

INDEX#

INts5v

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.

18

WPT#

INts5v

VCC Write protected. This active low Schmitt input from the

disk drive indicates that the diskette is write-protected.

19

DSKCHG#

INts5v

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

and whenever the diskette is removed.

Description

Infrared Transmitter Output.

General Purpose IO

Infrared Receiver input.

General Purpose IO.

Data Carrier Detect. An active low signal indicates the

modem or data set has detected a data carrier.

Ring Indicator. An active low signal indicates that a ring

signal is being received from the modem or data set.

Clear To Send is the modem control input.

UART 1 Data Terminal Ready. An active low signal

informs the modem or data set that controller is ready to

communicate. Internal 47k ohms pulled high and disable

after power on strapping.

Power on strapping pin:

1(Default): (Internal pull high)

Power on fan speed default duty is 60%.(PWM)

0: (External pull down)
