Section 10 Multi-Function Timer Pulse Unit (MTU)
This LSI has an on-chip multi-function timer pulse unit (MTU) that comprises five 16-bit timer
channels.
The block diagram is shown in figure 10.1.
10.1 Features
• Maximum 16-pulse input/output
• Selection of 8 counter input clocks for each channel
• The following operations can be set for each channel:
 Waveform output at compare match
 Input capture function
 Counter clear operation
Multiple timer counters (TCNT) can be written to simultaneously
Simultaneous clearing by compare match and input capture is possible
Register simultaneous input/output is possible by synchronous counter operation
 A maximum 12-phase PWM output is possible in combination with synchronous operation
• Buffer operation settable for channels 0, 3, and 4
• Phase counting mode settable independently for each of channels 1 and 2
• Cascade connection operation
• Fast access via internal 16-bit bus
• 23 interrupt sources
• Automatic transfer of register data
• A/D converter conversion start trigger can be generated
• Module standby mode can be set
• Positive and negative 3-phase waveforms (6-phase waveforms in total) can be output by
channel 3 and channel 4 connected in complementary PWM or reset PWM mode
• AC synchronous motor (brushless DC motor) drive mode can be set by channel 0, channel 3,
and channel 4 connected in complementary PWM or reset PWM mode.
• Selection of chopping or level waveform outputs in AC synchronous motor drive mode
