Section 18 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 18.1.
18.1 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
