Section 10 16-Bit Timer Pulse Unit (TPU)
This LSI has an on-chip 16-bit timer pulse unit (TPU) that comprises three 16-bit timer channels.
The function list of the 16-bit timer unit and its block diagram are shown in table 10.1 and figure
10.1, respectively.
10.1
Features
• Maximum 8-pulse input/output
• Selection of eight counter input clocks for channels 0 and 2, seven counter input clocks for
channel 1
• 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 possible
Register simultaneous input/output possible by counter synchronous operation
Maximum of 7-phase PWM output possible by combination with synchronous operation
• Buffer operation settable for channel 0
• Phase counting mode settable independently for each of channels 1 and 2
• Fast access via internal 16-bit bus
• 13 interrupt sources
• Automatic transfer of register data
• A/D converter conversion start trigger can be generated
