CONFIDENTIAL

 Multi-function Timer (Max 2units)

The Multi-function timer is composed of the following blocks.

 16-bit free-run timer × 3ch/unit

 Input capture × 4ch/unit

 Output compare × 6ch/unit

 A/D activation compare × 3ch/unit

 Waveform generator × 3ch/unit

 16-bit PPG timer × 3ch/unit

The following function can be used to achieve the motor control.

 PWM signal output function

 DC chopper waveform output function

 Dead timer function

 Input capture function

 A/D converter activate function

 DTIF (Motor emergency stop) interrupt function

 Quadrature Position/Revolution Counter (QPRC) (Max 2units)

The Quadrature Position/Revolution Counter (QPRC) is used to measure the position of the position

encoder. Moreover, it is possible to use up/down counter.

 The detection edge of the three external event input pins AIN, BIN and ZIN is configurable.

 16-bit position counter

 16-bit revolution counter

 Two 16-bit compare registers

 Dual Timer (32/16bit Down Counter)

The Dual Timer consists of two programmable 32/16-bit down counters.

Operation mode is selectable from the followings for each timer channel.

 Free-running

 Periodic (=Reload)

 One-shot

 Watch Counter

The Watch counter is used for wake up from Low-Power Consumption mode.

 Interval timer: up to 64s(Max)@ Sub Clock : 32.768kHz

 Watch dog Timer (2channels)

A watchdog timer can generate interrupts or a reset when a time-out value is reached.

This series consists of two different watchdogs, a "Hardware" watchdog and a, "Software" watchdog.

The "Hardware" watchdog timer is clocked by the built-in low speed CR oscillator. Therefore, the

"Hardware" watchdog is active in any low-power consumption modes except STOP mode.
