Note: When executing read instruction of this register, the contents of three-phase shift
register is read out.
Note 1: When the effective interrupt output specification bit (INV01: bit 1 at 0308
16
) is set to
"1" and three-phase motor control timer is operating, do not rewrite to this register.
Note 2: Do not write to this register at the timing of timer B2 overflow.
