Specification

Multi-function timer

pulse unit 2 (MTU2)

• Maximum 16 lines of pulse input/output based on five channels of 16-

bit timers

• 18 output compare and input capture registers

• A total of 18 independent comparators

• Selection of eight counter input clocks

• Input capture function

• Pulse output modes

One-shot, toggle, PWM, complementary PWM, and reset-synchronized

PWM modes

• Synchronization of multiple counters

• Complementary PWM output mode

⎯ Non-overlapping waveforms output for 6-phase inverter control

⎯ Automatic dead time setting

⎯ 0% to 100% PWM duty cycle specifiable

⎯ Output suppression

⎯ A/D conversion delaying function

⎯ Interrupt skipping at crest or trough

• Reset-synchronized PWM mode

Three-phase PWM waveforms in positive and negative phases can be

output with a required duty cycle

• Phase counting mode

Two-phase encoder pulse counting available

Multi-function timer

pulse unit 2S (MTU2S)

• Subset of MTU2, including channels 3 and 4

• Dead time compensation counter available in channel 5

• Operating at 80 MHz max. (T

opr = −40 to +85°C)

• Operating at 64 MHz max. (T

opr = −40 to +125°C)

Port output enable

(POE)

• High-impedance control of waveform output pins in MTU2 and MTU2S

Compare match timer

(CMT)

• 16-bit counters

• Compare match interrupts can be generated

• Two channels

Serial communication

interface (SCI)

• Clock synchronous or asynchronous mode

• Three channels
