Three-Phase Control Register 0

NOTES :
1.
Set the INVC0 register af ter the PRC1 bit in the PRCR register is set to "1" (write enable).
Rewrite the INV00 to INV02 and INV06 bits when Timers A1, A2, A4 and B2 stop.
2.
Set the INV01 bit to "1" af ter setting the ICTB2 register.
3.
The INV00 and INV01 bits are enabled only when the INV11 bit is set to "1" (three-phase mode 1). The ICTB2 counter is incremented by
one ev ery time Timer B2 underf lows, regardless of INV00 and INV01 bit settings, when the INV11 bit is set to "0" (three-phase mode).
When setting the INV01 bit to "1", set Timer A1 count start f lag bef ore the f irst Timer B2 underf low.
When the INV00 bit is set to "1", the f irst interrupt is generated when Timer B2 underf lows n -1 times, if n is the v alue set in the ICTB2
counter. Subsequent interrupts are generated ev ery n times Timer B2 underf lows.
4.
Set the INV02 bit to "1" to operate the dead time timer, U-, V-and W-phase output control circuits and ICTB2 counter.
5.
When the INVC03 bit is set to "1", the pins applied to U/V/W output three-phase PWM.

when the f ollowing conditions are all met.
• The INV02 bit is set to "1" (three-phase control timer f unction)
• The INV03 bit is set to "0" (three-phase control timer output disabled)
• Direction registers of each port are set to "0" (input mode)
6.
The INV03 bit is set to "0" when the f ollowings conditions are all met.
• Reset
• A concurrent activ e state occurs while INV04 bit is set to "1"
• The INV03 bit is set to "0" by program
• A signal applied to the NMI
When both the INVC04 and INVC05 bits are set to "1", the INVC03 bit is set to "0".
7.
The INV05 bit can not be set to "1" by program. Set the INV04 bit to "0", as well, when setting the INV05 bit to "0".
8.
The f ollowing table describes how the INV06 bit works.

Transf er trigger : Timer B2 underf lows and write to the INV07 bit, or write to the TB2 register when INV10 = 1
9.
When the INV06 bit is set to "1", set the INV11 bit to "0" (three-phase mode 0) and the PWCON bit in the TB2SC register to "0" (reload
Timer B2 with Timer B2 underf low).

16. Three-Phase Motor Control Timer Function
0 : The ICTB2 counter is incremented by one on the
(3) rising edge of Timer A1 reload control signal
1 : The ICTB2 counter is incremented by one on the
f alling edge of Timer A1 reload control signal
0 : ICTB2 counter is incremented by one when Timer B2
underf lows
1 : Selected by the INV00 bit
0 : No three-phase control timer functions
1 : Three-phase control timer function

Transf er trigger is generated when the INV07 bit is set to "1".
Trigger to the dead time timer is also generated when setting
the INV06 bit to "1". Its v alue is "0" when read.
