Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be “0”.
Note: When executing read instruction of this register, the contents of three-phase shift
register is read out.

Note1: In setting 1 to bit 1 (INV01) - the effective interrupt output specification bit - of three-
phase PWM control register 0, do not change the B2 interrupt occurrences frequency
set counter to deal with the timer function for three-phase motor control.
Note2: Do not write at the timing of an overflow occurrence in timer B2.
