6. Multifunction Timer
The multifunction timer unit is configured of a 16-bit freerun timer × 1, 16-bit output compare × 8, 16-bit input
capture × 4, 16-bit PPG timer × 6 ch and waveform generation area modules. 12 independent waveform outputs
based on a 16-bit free-run timer are possible using this function and measurement of input pulse width and
external clock cycle is also possible.

• 16-bit free-run timer ( × 1)
The 16-bit free-run timer consists of a 16-bit up counter, control register, 16-bit compare clear register and
pre-scalar. Output values of this counter are used as the base timer for output compare and input capture.
• Counter operation clocks can be selected from six types.
Six types of internal clocks (φ2, φ4, φ8, φ16, φ32, φ64)
φ : Machine clock
• Interruption can be generated by overflow of the counter value and a compared match with compare
clear register. (Mode setting is required for a compared match.)
• Counter value can be initialized to “0000H” by a compared match with the reset, software clear or the
compare clear register.
• Output compare ( × 8)
Output compare is configured of 16-bit compare register × 8, latch for compare output and control register.
Interruption can be generated as well as reversing output level when the 16-bit free-run timer value and compare
register value match.
• 8 compare registers can be operated independently. Output pins and interruption flags support each
compare register.
• Output pins can be controlled by pairing two compare registers. Output pins are reversed using two
compare registers.
• Initial value of each output pin can be set.
• Interruption can be generated by matching compare.
• Input capture ( × 4)
Input capture is configured with four independent external input pins , supported capture and control register.
16-bit free-run timer value is held in the capture register by detecting the random edge of signals that are input
by the external input pin, and interruption can simultaneously be generated.
• Valid edges (rising edge, falling edge, both edges) of external input signals can be selected.
• Four input captures can be operated independently.
• Interruption can be generated by the valid edges of external input signals.
• 16-bit PPG timer ( × 6)
