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
