NOTES :
1. Rew rite the INVC1 register after the PRC1 bit in the PRCR register is set to "1" (w rite enable).
The timers A1, A2, A4, and B2 must be stopped during rew rite.
2. The follow ing table lists how the INV11 bit w orks.
Item
Mode
TA11, TA21 and TA41
Registers
INV00 and INV01 Bit
INV13 Bit
3. When the INV06 bit is set to "1" (saw tooth w ave modulation mode), set the INV11 bit to "0" (three-phase mode 0).
Also, w hen the INV11 bit is set to "0", set the PWCON bit in the TB2SC register to "0" (Timer B2 is reloaded w hen
Timer B2 underflow s).
4. The INV13 bit is enabled only w hen the INV06 bit is set to "0" (Triangular w ave modulation mode) and the INV11 bit to
"1" (three-phase mode 1).
5. If the follow ing conditions are all met, set the INV16 bit to "1" (rising edge of the three-phase output shift register).
• The INV15 bit is set to "0" (dead time timer enabled)
• The Dij bit (i=U, V or W, j=0, 1) and DiBj bit alw ays have different values w hen the INV03 bit is set to "1".
(The positive-phase and negative-phase alw ays output opposite level signals.)
If above conditions are not met, set the INV16 bit to "0" (falling edge of a one-shot pulse of Timer A1, A2, A4).
