• Bit 0 – Lock Bit indicates the IC registers (Deadtime, MASKn, CLINTn, and Mode) are locked. Any subsequent write to
• 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

• 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
these registers is ignored and will set the Write Error flag.
IC can operate in FULLON Mode (both High-Side and Low-Side FETs of one phase can be simultaneously turned on).
includes the Zero Deadtime setting, as well as a Calibration Overflow.
