                                     through the write head.
                                     It becomes active just prior to writing to the diskette.
  14   AFD#/DSB#_D14,_P14/_D12:O     This output goes low to cause the printer to
       ,O/O                          automatically feed one line after each line is printed.
                                     The AFD# output is the complement of bit 1 of the
                                     printer control register. Refer to parallel pot description
                                     for use of this pin in ECP and EPP mode.
  15   ERR#/HDSEL_T/D12:I/O          A low on this input from the printer indicates that there is
                                     a error condition at the printer. Bit 3 of the printer status
                                     register reads the ERR# input. Refer to
                                     Parallel port description for use of this pin in ECP and
                                     EPP mode. This high current output selects the floppy
                                     Disk side for reading or writing. A logic "1" on this pin
                                     means side 0 will be accessed while a logic "0" means
                                     side 1 will be accessed.
  16   INIT#/DIR#_D14,_P14/D12:O,O   This output is bit 2 of the printer control register. This is
       /O                            used to initiate the printer when low. Refer to parallel
                                     port description for use of this pin in ECP and EPP

                             low active. Each falling edge represents a flux transition
                             of the encoded data.
      9         WGATE#       Write gate. This active low high current driver allows         O
                             current to flow through the write head.
                             It becomes active just prior to writing to the diskette.
     11         WDATA#       Write data. This active low high current driver provides       O
                             the encoded data to the disk drive.
                             Each falling edge causes a flux transition on the media.

                             for reading or writing. A logic "1" on the pin means side 0
                             will be accessed, while a logic "0" means side 1 will be
                             accessed.

                             determines the direction of the head movement. A logic
                             "1" on this pin means outward motion, while a logic "0"
                             means inward motion.
     13          STEP#       Step pulse. The active low high current driver issues a        O
                             low pulse for each track-to-track movement of the head.
     21         DSKCHG#      Disk change. This input senses that the drive door is          I
                             open or that the diskette has possibly been changed
                             since the last drive selection.
                             This input is inverted and read via bit 7 of I/O address
                             3F7H. The DSKCHG# bit also depends upon the state of
                             the Force Disk Change bits in the Force FDD Status
                             Change configuration register.

                             senses from the disk drive that a disk is write protected.
      7          TRK0#       Track 00. This active low Schmitt trigger input senses         I
                             from the disk drive that the head is positioned over the
                             outermost track.
