Section 9 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 9.1 and figure

9.1, respectively.

9.1

Features

• Maximum 8-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,

simultaneous writing to multiple timer counters (TCNT), simultaneous clearing using compare

match or input capture, simultaneous input/output for individual registers using counter

synchronous operation, PWM output using user-defined duty, up to 7-phase PWM output 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

• Module stop mode can be set

• Baud rate clock for the SCI0 can be generated
