== Accessing the FDC 765 ==
The recommended ports used by Amstrad and compatible interfaces are:
{| class="wikitable"
|-
!I/O port address
!Function
|-
|&FA7E||Floppy Motor On/Off Flipflop
|-
|&FB7E||FDC 765 Main Status Register (read only)
|-
|&FB7F||FDC 765 Data Register (read/write)
|}
The Main Status Register signalizes when the FDC is ready to send/receive the next byte through the Data Register.
