V phase output buffer 0 Setting in V phase output buffer 0 (Note)
DVB0 V phase output buffer 0 Setting in V phase output buffer 0 (Note)
DW0
W phase output buffer 0 Setting in W phase output buffer 0 (Note)
DWB0 W phase output buffer 0 Setting in W phase output buffer 0 (Note)
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.

Dead time timer (Note)
b7
b0
Symbol
DTT
Address
034C16
When reset
Indeterminate
Function
Values that can be set R W
Set dead time timer
1 to 255
Note: Use MOV instruction to write to this register.
Timer B2 interrupt occurrences frequency set counter (Note 1, 2, 3)
b3
b0
Symbol
Address
When reset
ICTB2
034D16
Indeterminate
Function
Values that can be set ^{R W}
Set occurrence frequency of timer B2
interrupt request
1 to 15
Note 1: 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.
Note 2: Do not write at the timing of an overflow occurrence in timer B2.
Note 3: Use MOV instruction to write to this register.
