Section 8 Multifunction Timer Pulse Unit (MTU)
Section 8 Multifunction Timer Pulse Unit (MTU)
This LSI has an on-chip multifunction timer pulse unit (MTU) that comprises five 16-bit timer
channels.
The block diagram is shown in figure 8.1.
8.1 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 in
complementary or reset synchronous PWM mode by combining channels 3 and 4.
• AC synchronous motor (brushless DC motor) can be driven in complementary or reset
synchronous PWM mode by combining channels 0, 3, and 4. Chopping or level output can be
selected as drive waveform output.
