FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Status Register 1 (MODE Bits)
This register is read by sending the NULL1 command (000x xx01). This is guaranteed to not affect IC operation and returns
the following data:
Status Register 2
(MASK bits)
This register is read by sending the NULL2 command (000x xx10). This is guaranteed to not affect IC operation and returns
the following data:
Status Register 3
(Deadtime)
This register is read by sending the NULL3 command (000x xx11). This is guaranteed to not affect IC operation and returns
the following data:

Bit 0
–
Lock Bit
indicates the IC registers (Deadtime, MASKn, CLINTn, and Mode) are locked. Any subsequent write to
these registers is ignored and will set the Write Error flag.
Bit 1
– is the present status of
FULLON
Mode
. If this bit is set to “0”, the FULLON mode is not allowed. A “1” indicates the
IC can operate in FULLON Mode (both High-Side and Low-Side FETs of one phase can be simultaneously turned on).
Bit 3
–indicates
Deadtime
Calibration
occurred. It will be “0” until a successful Deadtime command is executed. This
includes the Zero Deadtime setting, as well as a Calibration Overflow.
Bit 4
–is a flag for a Deadtime
Calibration Overflow
.
Bit 5
–is set if
Zero Deadtime
is commanded.
Bit 6
–reflects the current state of the
Desaturation/Phase Error turn-off
mode.

These bits represent the calibration applied to the internal oscillator to generate the requested deadtime. If calibration is not
yet performed, all these bits return 0 even though the actual dead time is the maximum.
