| description: | |
| This hardware block consists of eight 16-bit timer channels and one |
| 32- bit timer channel. It supports the following specifications: |
| - Pulse input/output: 28 lines max. |
| - Pulse input 3 lines |
| - Count clock 11 clocks for each channel (14 clocks for MTU0, 12 clocks |
| for MTU2, and 10 clocks for MTU5, four clocks for MTU1-MTU2 combination |
| (when LWA = 1)) |
| - Operating frequency Up to 100 MHz |
| - Available operations [MTU0 to MTU4, MTU6, MTU7, and MTU8] |
| - Waveform output on compare match |
| - Input capture function (noise filter setting available) |
| - Counter-clearing operation |
| - Simultaneous writing to multiple timer counters (TCNT) |
| (excluding MTU8). |
| - Simultaneous clearing on compare match or input capture |
| (excluding MTU8). |
| - Simultaneous input and output to registers in synchronization with |
| counter operations (excluding MTU8). |
| - Up to 12-phase PWM output in combination with synchronous operation |
| (excluding MTU8) |
| - [MTU0 MTU3, MTU4, MTU6, MTU7, and MTU8] |
| - Buffer operation specifiable |
| - [MTU1, MTU2] |
| - Phase counting mode can be specified independently |
| - 32-bit phase counting mode can be specified for interlocked operation |
| of MTU1 and MTU2 (when TMDR3.LWA = 1) |
| - Cascade connection operation available |
| - [MTU3, MTU4, MTU6, and MTU7] |
| - Through interlocked operation of MTU3/4 and MTU6/7, the positive and |
| negative signals in six phases (12 phases in total) can be output in |
| complementary PWM and reset-synchronized PWM operation. |
| - In complementary PWM mode, values can be transferred from buffer |
| registers to temporary registers at crests and troughs of the timer- |
| counter values or when the buffer registers (TGRD registers in MTU4 |
| and MTU7) are written to. |
| - Double-buffering selectable in complementary PWM mode. |
| - [MTU3 and MTU4] |
| - Through interlocking with MTU0, a mode for driving AC synchronous |
| motors (brushless DC motors) by using complementary PWM output and |
| reset-synchronized PWM output is settable and allows the selection |
| of two types of waveform output (chopping or level). |
| - [MTU5] |
| - Capable of operation as a dead-time compensation counter. |
| - [MTU0/MTU5, MTU1, MTU2, and MTU8] |
| - 32-bit phase counting mode specifiable by combining MTU1 and MTU2 and |
| through interlocked operation with MTU0/MTU5 and MTU8. |
| - Interrupt-skipping function |
| - In complementary PWM mode, interrupts on crests and troughs of counter |
| values and triggers to start conversion by the A/D converter can be |
| skipped. |
| - Interrupt sources: 43 sources. |
| - Buffer operation: |
| - Automatic transfer of register data (transfer from the buffer |
| register to the timer register). |
| - Trigger generation |
| - A/D converter start triggers can be generated |
| - A/D converter start request delaying function enables A/D converter |
| to be started with any desired timing and to be synchronized with |
| PWM output. |
| - Low power consumption function |
| - The MTU3a can be placed in the module-stop state. |
| |
| There are two phase counting modes. 16-bit phase counting mode in which |
| MTU1 and MTU2 operate independently, and cascade connection 32-bit phase |
| counting mode in which MTU1 and MTU2 are cascaded. |
| |
| In phase counting mode, the phase difference between two external input |
| clocks is detected and the corresponding TCNT is incremented or |
| decremented. |
| The below counters are supported |
| count0 - MTU1 16-bit phase counting |
| count1 - MTU2 16-bit phase counting |
| count2 - MTU1+ MTU2 32-bit phase counting |
| |
| The module supports PWM mode{1,2}, Reset-synchronized PWM mode and |
| complementary PWM mode{1,2,3}. |
| |
| In complementary PWM mode, six positive-phase and six negative-phase PWM |
| waveforms (12 phases in total) with dead time can be output by |
| combining MTU{3,4} and MTU{6,7}. |
| |
| The below pwm channels are supported in pwm mode 1. |
| pwm0 - MTU0.MTIOC0A PWM mode 1 |
| pwm1 - MTU0.MTIOC0C PWM mode 1 |
| pwm2 - MTU1.MTIOC1A PWM mode 1 |
| pwm3 - MTU2.MTIOC2A PWM mode 1 |
| pwm4 - MTU3.MTIOC3A PWM mode 1 |
| pwm5 - MTU3.MTIOC3C PWM mode 1 |
| pwm6 - MTU4.MTIOC4A PWM mode 1 |
| pwm7 - MTU4.MTIOC4C PWM mode 1 |
| pwm8 - MTU6.MTIOC6A PWM mode 1 |
| pwm9 - MTU6.MTIOC6C PWM mode 1 |
| pwm10 - MTU7.MTIOC7A PWM mode 1 |
| pwm11 - MTU7.MTIOC7C PWM mode 1 |
