Section 14 16-Bit Timer Pulse Unit (TPU)
Microcontrollers of the H8/38099 Group have an on-chip 16-bit timer pulse unit (TPU) that
comprises two 16-bit timer channels. The function list of the TPU is shown in table 14.1. A block
diagram of the TPU is shown in figure 14.1.
14.1 Features
Maximum 4-pulse input/output
Selection of 7 or 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 synchronous input/output is possible by synchronous counter operation
PWM output with any duty level is possible
A maximum 3-phase PWM output is possible in combination with synchronous operation
Operation with cascaded connection
Fast access via internal 16-bit bus
6-type interrupt sources
Module standby mode enables this module to be placed in standby mode independently when
it is not in use (for details, refer to section 6.4, Module Standby Function).
