Three-phase output buffer register 0
b7 b6 b5 b4 b3 b2 b1 b0
Symbol
IDB0
Address
034A16
When reset
3F16
Bit Symbol
DU0
Bit name
U phase output buffer 0
Function
Setting in U phase output buffer 0
RW
DUB0 U phase output buffer 0 Setting in U phase output buffer 0
DV0
V phase output buffer 0 Setting in V phase output buffer 0
DVB0
V phase output buffer 0 Setting in V phase output buffer 0
DW0
W phase output buffer 0 Setting in W phase output buffer 0
DWB0 W phase output buffer 0 Setting in W phase output buffer 0
Nothing is assigned.
Write "0" when writing to these bits. If read, the value is "0".
Note: When executing read instruction of this register, the contents of three-phase shift
register is read out.

DUB1 U phase output buffer 1 Setting in U phase output buffer 1
DV1
V phase output buffer 1 Setting in V phase output buffer 1
DVB1
V phase output buffer 1 Setting in V phase output buffer 1
DW1

DWB1 W phase output buffer 1 Setting in W phase output buffer 1
Nothing is assigned.
Write "0" when writing to these bits. If read, the value is "0".
Note: When executing read instruction of this register, the contents of three-phase shift
register is read out.
Dead time timer
b7
b0
Symbol
DTT
Address
034C16
When reset
Indeterminate
Function
Set dead time timer
Values that can be set R W
1 to 255
Timer B2 interrupt occurrences frequency set counter
b3
b0
Symbol
Address
When reset
ICTB2
034D16
Indeterminate
Function
Set occurrence frequency of Timer B2
interrupt request
Values that can be set ^{R W}
1 to 15
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.
Note 2: Do not write at the timing of an overflow occurrence in Timer B2
