Indicates whether a low (250/300 Kb/s) or
high (500 Kb/s) data rate has been selected.
Configuration Register 3.
This active low Schmitt Trigger input senses
from the disk drive that a disk is write
protected. Any write command is ignored.
This active low Schmitt Trigger input senses
from the disk drive that the head is
positioned over the outermost track.
This active low Schmitt Trigger input senses
from the disk drive that the head is
positioned over the beginning of a track, as
marked by an index hole.
These two outputs reflect bits 0 and 1
respectively of the Data Rate Register. At
power on, these two outputs are in a high
impedance state (refer to Table 50).
In Floppy Enhanced Mode 2 - These bits are
the Media ID 0,1 inputs. The value of these
bits can be read as bits 6 and 7 of the
Floppy Tape register.
Receiver serial data input.
Transmitter serial data output from Primary
Serial Port.
FDC37C666GT (Adapter Mode): Parallel
Port Configuration Control 0. During reset
active this input is read and latched to
define the address of the Parallel Port.
This is determined by the IDENT bit in
