These two registers select FDC I/O base address <100h : FF8h> on 8
bytes boundary.
These bits select IRQ resource for FDC.
These bits select DRQ resource for FDC.
000: DMA0.
1xx: No DMA active.
This bit controls the internal pull-up resistors of the FDC input pins
RDATA#, INDEX#, TRAK0#, DSKCHG# and WP#.
0: The internal pull-up resistors of FDC are turned on.
1: The internal pull-up resistors of FDC are turned off. (Default)
This bit determines the polarity of all FDD interface signals.
0: FDD interface signals are active low.
1: FDD interface signals are active high.
001: DMA1.
