Dead time timer (Note)

Symbol

Address

When reset

034C16

Indeterminate

Function

Values that can be set

Set dead time timer

to 255

Timer B2 interrupt occurrences frequency set counter (Note 1, 2, 3)

Symbol

Address

When reset

ICTB2

034D16

Indeterminate

Function

Values that can be set

Set occurrence frequency of timer B2

interrupt request

1 to 15

Note: When executing read instruction of this register, the contents of three-phase shift

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.

(Note)

Note: Use MOV instruction to write to this register.
