INV03 (Three-phase motor control timer output control bit) (b3)
Conditions to become 0:
•
The INV04 bit is 1 (simultaneous turn-on disabled) and the INV05 bit is 1 (simultaneous turn-on
detected).
•
The INV03 bit is set to 0 by a program.
The signal applied to the SD pin is low.
•
INV05 (High- and low-side simultaneous turn-on detect flag) (b5)
The INV05 bit cannot be set to 1 by a program. Set the INV04 bit to 0 when setting the INV05 bit to 0.
INV06 (Modulation mode select bit) (b6)
The following table lists items influenced by the INV06 bit.
Table 17.4
Influence of the INV06 Bit
Item
Mode
Transfer timing from
registers IDB0 and
IDB1 to three-phase
output shift register
Trigger timing of the
dead time timer when
the INV16 bit is 0
INV13 bit
One of the following conditions must be met to trigger a transfer:
•
Timer B2 underflows.
•
A value is written to the INV07 bit.
•
A value is written to the TB2 register during timer B2 stop when the INV10 bit is 1.
