FDC37C666GT Software Configuration
-
Differences from FDC37C665GT
All software configuration options available for
the FDC37C665GT are available for the
FDC37C666GT
except
selected by the hardware configuration pins. The
options set by hardware configuration in the
FDC37C666GT that cannot be changed by
software are:
for
those
options
Parallel Port Address (set by PCF1, PCF0)
Parallel Port Mode (Set by ECPEN and PADCF)
Serial Port Address (Set by S1CF1, S1CF0,
S2CF1, S2CF0)
IDE Control (Set by IDECF, IDEACF)
FDC Control (if FDCCF=1, Set by FACF, If
FDCCF=0
can
be
configuration)
changed
in
software
The location of the configuration select registers
(CSR) can be moved to 370H and the
configuration registers 0-F can be accessed at
port 371H by setting FDCCF=0 and FACF=1.
To enter the configuration mode of the
FDC37C666GT, two writes in succession to the
CSR (port 3F0H or 370H see FDCCF and
FACF) with 44H 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. The configuration mode is
exited by writing an AAH to the CSR.
In the FDC37C666GT, the pins used to
configure the part should be connected as per
the diagram below. This shows how a jumper
can be used to set a high (VCC) or a low (GND)
into the port for configuration at the end of the
reset pulse.
