(1) Setting procedure
(a) The TW0UDC count clock is set with the TCL00 to TCL02 bits of inverter timer control register (TW0C) and
(b) The active level of the TW0TO0 to TW0TO5 pins is set with the ALV0 bit of inverter timer mode register
(c) Set the half width of the first PWM cycle to 10-bit compare register 3 (TW0CM3).
(d) Set the half width of the second PWM cycle to 10-bit buffer register 3 (TW0BFCM3).
(e) Set the dead time width to the dead time reload register (TW0DTIME).
(f)
(g) Set the F/F set/reset timing that is used during the second cycle to TW0BFCM3.
(h) After the CE0 bit of TW0C is set (1), the operation of TW0UDC, dead-time timers 0 to 2 (DTM0 to DTM2),
(i)
(j)
Registers Controlling 10-Bit Inverter Control Timer
the occurrence frequency of interrupt request signal INTTW0UD is set with the IDEV00 to IDEV02 bits.
(TW0M).
Set the F/F set/reset timing that is used during the first cycle to 10-bit compare registers 0 to 2 (TW0CM0 to
TW0CM2).
and buffer transfer control timer (RTM0) is enabled.
Caution Always use a bit manipulation instruction to set the CE0 bit.
Set the F/F set/reset timing that is used for the next cycle to TW0BFCM0 to TW0BFCM5 during TW0UDC
operation.
To stop the TW0UDC operation, set the CE0 bit of the TW0C to 0.
Caution Another bit cannot be rewritten at the same time that the CE0 bit is being rewritten.
PWM cycle = TW0CM3 value
(The clock rate of TW0UDC is set with the TW0C)
Dead time width = (TW0DTIME + 1)
