CR0
This register can only be accessed when the
FDC is in the Configuration Mode and after the
CSR has been initialized to 00H. The default
value of this register after power up is 3BH for
the FDC37C665IR.

BIT NAME
IDE ENABLE
DESCRIPTION
A high level on this bit, enables the IDE (Default). A low level on
this bit disables the IDE.
A high level on this bit sets the IDE to AT type (Default). A low
level on this bit sets the IDE to XT type.
(This bit is Reserved - set to '0').
A high level on this bit, supplies power to the FDC (default for the
FDC37C665IR). A low level on this bit puts the FDC in low
power mode.
A high level on this bit, enables the FDC (Default). A low level on
this bit disables the FDC.
6 5
0 0Osc ON, Baud Rate Generator (BRG) Clock Enabled.
0 1Osc is On, BRG Clock is ON when PWRGD is active. When
PWRGD is inactive, Osc is off and BRG Clock is
Disabled (Default).
1 0(same as 0 1 case)
1 1Osc OFF, BR Generator Clock Disabled
A high level on this software controlled bit indicates that a valid
configuration cycle has occurred. The control software must take
care to set this bit at the appropriate times. Set to zero after
power up.
