Step output pulses. This active low open drain output produces a
pulse to move the head to another track.
This schmitt input from the disk drive is active low when the head is
positioned over the beginning of a track marked by an index hole.
This input pin is pulled up internally by an approximately 1K ohm
resistor. The resistor can be disabled by bit 4 of CR6 (FIPURDWN).
Track 0. This schmitt input from the disk drive is active low when the
head is positioned over the outermost track. This input pin is pulled
up internally by an approximately 1K ohm resistor. The resistor can
be disabled by bit 4 of CR6 (FIPURDWN).
Write protected. This active low schmitt input from the disk drive
indicates that the diskette is write-protected. This input pin is pulled
up internally by an approximately 1K ohm resistor. The resistor can
be disabled by bit 4 of CR6 (FIPURDWN).
The read data input signal from the FDD. This input pin is pulled up
internally by an approximately 1K ohm resistor. The resistor can be
disabled by bit 4 of CR6 (FIPURDWN).
Diskette change. This signal is active low at power on and whenever
the diskette is removed. This input pin is pulled up internally by an
approximately 1K ohm resistor. The resistor can be disabled by bit 4
of CR6 (FIPURDWN).
Motor A On. When set to 0, this pin enables disk drive 0. This is an
open drain output.
Motor B On. When set to 0, this pin enables disk drive 1. This is an
open drain output.
Drive Select A. When set to 0, this pin enables disk drive A. This is
an open drain output.
Drive Select B. When set to 0, this pin enables disk drive B. This is
an open drain output.
