Symbol
Address
When reset
ICTB2
030D16
Indeterminate
Function
Values that can be set ^{R W}

Note 1: When the effective interrupt output specification bit (INV01: bit 1 at 030816) 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.
Note 3: Use MOV instruction to write to this register.
Note 4: Setting of this register is valid only when bit 2(INV02) of three-phase PWM control
register 0 is set to "1".
