7.1 Outline of Functions
(hereinafter referred to as “TAUS”) and the TAUS option unit. It can be used with an operation clock having a 40 MHz
maximum resolution (when the internal high-speed oscillation clock is used). Furthermore, the A/D converter start
timing can be generated.

The 78K0R/IE3 can be used as an inverter control function and for motor control by using timer array unit TAUS
The following operations can be performed by using the inverter control function.
(1) Complementary PWM output function
• 6-phase PWM output function (triangular wave modulation, upper arm, lower arm, six outputs)
• Half-bridge output function (two outputs × 2)
• Full-bridge output function (four outputs)
A waveform of an arbitrary period, the duty, and the dead time can be generated by using channel 7 of the
TAUS in combination.
→ refer to 7.5.6 Operation as 6-phase triangular wave PWM output function
A waveform of an arbitrary period, the duty, and the dead time can be generated by using channel 3 of the
TAUS in combination.
→ refer to 7.5.5 Operation as triangular wave PWM output function with dead time
This function uses the above-mentioned half-bridge output.
