CONFIGURATION
The configuration of the FDC37C665IR within
the user system is selected through software
selectable configuration registers.
FDC37C665IR CONFIGURATION REGISTERS
The configuration registers are used to select
programmable options of the FDC. After power
up, the FDC is in the default mode. The default
modes are identified in the Configuration Mode
Register
Description.
configuration registers, the following sequence
must be followed:
To
program
the
1.Enter Configuration Mode.
2.Configure FDC Registers.
3.Exit Configuration Mode.
Enter Configuration Mode
To enter the configuration mode of the
FDC37C665IR, two writes in succession to port
3F0H with 55H data are required. If a write to
another address or port occurs between these
two writes, the chip does not enter the
configuration mode. It is strongly recommended
that interrupts be disabled for the duration of
these two writes.
Configure FDC37C665IR
The
configuration registers, CR0-CRF. These
registers are accessed by first writing the
number (0-F) of the desired register to port
3F0H and then writing or reading the
configuration register through port 3F1H.
FDC37C665IR
contains
SIXTEEN
Exit Configuration Mode
The configuration mode is exited by writing an
AAH to port 3F0H.
Programming Example
The following is an example of a configuration
program in Intel 8086 assembly language. For
this example, the FDC37C665IR is being reset
to the default condition after power up.
