NOTES:
1. Set the INVC0 register after the PRC1 bit in the PRCR register is set to 1 (write enable). Set bits INV06 and INV02 to INV00
2. Set the INV01 bit to 1 after setting a value to the ICTB2 register. Also, when the INV01 bit is set to 1, set the timer A1 count start
3. Set pins after the INV02 bit is set to 1. Refer to the table, Pin settings when using three-phase motor control timer function .
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 INV03 bit is set to 0 and the INV02 bit to 1, pins U, U, V, V, W, and W (including when other output functions are
6. The INV03 bit becomes 0 when one of the following occurs:
7. The INV05 bit cannot be set to 1 by a program. To set the INV05 bit to 0, write a 0 to the INV04 bit.
while timers A1,A2, A4, and B2 are stopped.

assiged to these pins) are all placed in high-impedance states.
-Reset
-The both upper and lower arms output the active level signals at the same time while the INV04 bit is set to 1
-The INV03 bit is set to 0 by a program
-Signal applied to the NMI pin changes from "H" to "L" (while an "L" is applied to the NMI pin, the INV03 bit cannot be set to 1).
