13 This hardware block consists of eight 16-bit timer channels and one
14 32-bit timer channel. It supports the following specifications:
15 - Pulse input/output: 28 lines max
16 - Pulse input 3 lines
17 - Count clock 11 clocks for each channel (14 clocks for MTU0, 12 clocks
18 for MTU2, and 10 clocks for MTU5, four clocks for MTU1-MTU2 combination
19 (when LWA = 1))
20 - Operating frequency Up to 100 MHz
21 - Available operations [MTU0 to MTU4, MTU6, MTU7, and MTU8]
22 - Waveform output on compare match
23 - Input capture function (noise filter setting available)
24 - Counter-clearing operation
25 - Simultaneous writing to multiple timer counters (TCNT)
26 (excluding MTU8)
27 - Simultaneous clearing on compare match or input capture
28 (excluding MTU8)
29 - Simultaneous input and output to registers in synchronization with
30 counter operations (excluding MTU8)
31 - Up to 12-phase PWM output in combination with synchronous operation
32 (excluding MTU8)
33 - [MTU0 MTU3, MTU4, MTU6, MTU7, and MTU8]
34 - Buffer operation specifiable
35 - [MTU1, MTU2]
36 - Phase counting mode can be specified independently
37 - 32-bit phase counting mode can be specified for interlocked operation
38 of MTU1 and MTU2 (when TMDR3.LWA = 1)
39 - Cascade connection operation available
40 - [MTU3, MTU4, MTU6, and MTU7]
41 - Through interlocked operation of MTU3/4 and MTU6/7, the positive and
42 negative signals in six phases (12 phases in total) can be output in
43 complementary PWM and reset-synchronized PWM operation
44 - In complementary PWM mode, values can be transferred from buffer
45 registers to temporary registers at crests and troughs of the timer-
46 counter values or when the buffer registers (TGRD registers in MTU4
47 and MTU7) are written to
48 - Double-buffering selectable in complementary PWM mode
49 - [MTU3 and MTU4]
50 - Through interlocking with MTU0, a mode for driving AC synchronous
51 motors (brushless DC motors) by using complementary PWM output and
52 reset-synchronized PWM output is settable and allows the selection
53 of two types of waveform output (chopping or level)
54 - [MTU5]
55 - Capable of operation as a dead-time compensation counter
56 - [MTU0/MTU5, MTU1, MTU2, and MTU8]
57 - 32-bit phase counting mode specifiable by combining MTU1 and MTU2 and
58 through interlocked operation with MTU0/MTU5 and MTU8
59 - Interrupt-skipping function
60 - In complementary PWM mode, interrupts on crests and troughs of counter
61 values and triggers to start conversion by the A/D converter can be
62 skipped
63 - Interrupt sources: 43 sources.
64 - Buffer operation:
65 - Automatic transfer of register data (transfer from the buffer
66 register to the timer register).
67 - Trigger generation
68 - A/D converter start triggers can be generated
69 - A/D converter start request delaying function enables A/D converter
70 to be started with any desired timing and to be synchronized with
71 PWM output
72 - Low power consumption function
73 - The MTU3a can be placed in the module-stop state
74
75 There are two phase counting modes. 16-bit phase counting mode in which
76 MTU1 and MTU2 operate independently, and cascade connection 32-bit phase
77 counting mode in which MTU1 and MTU2 are cascaded.
78
79 In phase counting mode, the phase difference between two external input
80 clocks is detected and the corresponding TCNT is incremented or
81 decremented.
82 The below counters are supported
83 count0 - MTU1 16-bit phase counting
84 count1 - MTU2 16-bit phase counting
85 count2 - MTU1+ MTU2 32-bit phase counting
86
87 The module supports PWM mode{1,2}, Reset-synchronized PWM mode and
88 complementary PWM mode{1,2,3}.
89
90 In complementary PWM mode, six positive-phase and six negative-phase PWM
91 waveforms (12 phases in total) with dead time can be output by
92 combining MTU{3,4} and MTU{6,7}.
93
94 The below pwm channels are supported in pwm mode 1.
95 pwm0 - MTU0.MTIOC0A PWM mode 1
96 pwm1 - MTU0.MTIOC0C PWM mode 1
97 pwm2 - MTU1.MTIOC1A PWM mode 1
98 pwm3 - MTU2.MTIOC2A PWM mode 1
99 pwm4 - MTU3.MTIOC3A PWM mode 1
100 pwm5 - MTU3.MTIOC3C PWM mode 1
101 pwm6 - MTU4.MTIOC4A PWM mode 1
102 pwm7 - MTU4.MTIOC4C PWM mode 1
103 pwm8 - MTU6.MTIOC6A PWM mode 1
104 pwm9 - MTU6.MTIOC6C PWM mode 1
105 pwm10 - MTU7.MTIOC7A PWM mode 1
106 pwm11 - MTU7.MTIOC7C PWM mode 1
