Description
8-bit PWM
timer
(PWMU)
• 8-bit timers A/B × six channels
• Selectable from four clock sources
• Cycle selectable for each channel
• Supports 8-bit single pulse mode, 16-bit single pulse mode, and
8-bit pulse division mode.
14-bit PWM
timer
(PWMX)
• 14 bits × two channels
• Pulse division method
• Selectable from sixteen operation clocks by combination of
eight system clock cycles and two base cycles
16-bit timer
pulse unit
(TPU)
• 16 bits × three channels
• Selectable from eight counter input clocks for each channel
• Maximum 8-pulse inputs/outputs
• The following operations can be set.
⎯ 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
• Supports buffer operation and phase counting mode (two-
phase encoder input) for some channels
• Supports input capture function
• Supports output compare function (waveform output at
compare match)
Timer

period
measurem-
ent timer
(TDP)
• 16 bits × three channels
