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

 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
