Features

Power-down modes

• Four power-down modes provided to reduce the current consumption

in this LSI

 Sleep mode

 Software standby mode

 Deep standby mode

 Module standby mode

Multi-function timer

pulse unit 2 (MTU2)

• Maximum 16 lines of pulse inputs/outputs and 3 lines of pulse inputs

based on six channels of 16-bit timers

• 21 output compare and input capture registers

• 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 3-phase inverter control

 Automatic dead time setting

 0% to 100% PWM duty cycle specifiable

 A/D converter start request 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 value

• Phase counting mode

Two-phase encoder pulse counting available

8-bit timer (TMR)

• Two-channel 8-bit timer

• Six internal clocks (Pφ/2, Pφ/8, Pφ/32, Pφ/64, Pφ/1024, or Pφ/8192) or

external clock specifiable

• Timer outputs controllable using two compare match signals

• Two channels can be cascade-connected

Realtime clock (RTC)

• Internal clock, calendar function, alarm function

• Interrupts can be generated at intervals of 1/256 s by the 32.768-kHz

on-chip crystal oscillator
