Preliminary Specification
This is a preliminary specification and is subject to change.
19. Three-Phase Motor Control Timer Function
INV03 (Three-Phase Motor Control Timer Output Control Bit) (b3)
Conditions to become 0:
• Reset
• 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.
• A 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 as well when setting the INV05 bit
to 0.
INV06 (Modulation Mode Select Bit) (b6)
The following table describes the influence the INV06 bit.
Table 19.4 INV06 Bit
Item
INV06 = 0
INV06 = 1
Mode
Triangular wave modulation mode
Sawtooth wave modulation 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
Transferred once by generating a
transfer trigger after setting registers
IDB0 and IDB1
Falling edge of a one-shot pulse of the
timers A1, A2, or A4
Transferred every time a transfer trigger
is generated
• Falling edge of a one-shot pulse of the
timer A1, A2, or A4
• Transfer trigger
INV13 bit
Enabled when the INV11 bit is 1 and the Disabled
INV06 bit is 0
One of the following conditions must be met to trigger a transfer:
• Timer B2 underflows and a value is written to the INV07 bit
• A value is written to the TB2 register when the INV10 bit is 1
