Configures how the controller is turned on and off.
The Write_Protect command is used to control writing to the I
device. There is also a lock bit in the Manufacture Specific Registers
that once set will disable writes to all commands until the power to the
NCP4200 is cycled.
This command allows the host to get some information on the I
device.

00xx xxxx – Immediate Off
01xx xxxx – Soft Off
1000 xxxx – On (slew rate set by soft−start) − Default
1001 10xx – Margin Low (Act on Fault)
1010 10xx – Margin High (Act on Fault)
Bit
7:5
Writing any value to this command code will clear all Status Bits
immediately. The SMBus ALERT is deasserted on this command. If
the fault is still present the fault bit shall immediately be asserted
again.
Bit
6:5
3:0
The NCP4200 supports VID mode for programming the output
voltage.
Sets the output voltage using VID.
Sets the output voltage when operation command is set to Margin
High. Programmed in VID Mode.

Reserved for Future Use
This bit is read only. Switching starts when
commanded by the Control Pin and the
Operation Command, as set in Bits 3:0.
0: Unit ignores OPERATION commands over
the I
1: Unit responds to OPERATION command,
powerup may also depend upon Control input,
as described in Bit 2
0: Unit ignores EN pin
1: Unit responds EN pin, powerup may also
depend upon the Operation Register, as
described for Bit 3
Control Pin polarity
0 = Active Low
1 = Active High
This bit is read only.
1: means that when the controller is disabled it
will either immediately turn off or soft off (as set
in the Operation Command)
Disables all writes except to the Write_Protect
Command
Disables all writes except to the Write_Protect
and Operation Commands
Disables all writes except to the Write_Protect,
Operation, ON_OFF_Config and
VOUT_COMMAND Commands
Enables writes to all commands
Disables all writes except to
WRITE_PROTECT, PAGE and all
MFR−SPECIFIC Commands
PEC (Packet Error Checking is supported)
