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 • Maximum 16 lines of pulse inputs/outputs and 3 lines of pulse inputs
pulse unit 2 (MTU2)
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
