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:

? 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.
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:

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.
