source select bit
0 : f1 or f2
1 : f1 divided by 2, or f2 divided by 2
INV13
INV14
Carrier wave detect flag
0: Rising edge of triangular waveform
1: Falling edge of triangular waveform
(Note 2)
(Note 4)
Output polarity control bit 0 : Low active
1 : High active
INV15 ^{Dead time invalid bit}
0: Dead time valid bit
1: Dead time invalid bit
INV16

(Note 3)
(b7)
Reserved bit
This bit should be set to "0".
Note 1: Set bit 1 of the protect register (address 000A16) to 1 before writing to this register.
Note 2: INV13 is valid only in triangular waveform mode (INV06=0) and three-phase mode (INV11=1).
Note 3:Usually set to 1 .
Note 4: When INV14="1", INV13="0" is falling edge of triangular waveform and INV13="1" is rising edge of triangular
waveform.
