CONFIDENTIAL

 Base Timer (Max eight channels)

Operation mode is selectable from the followings for each channel.

 16-bit PWM timer

 16-bit PPG timer

 16-/32-bit reload timer

 16-/32-bit PWC timer

 General-Purpose I/O Port

This series can use its pins as general-purpose I/O ports when they are not used for peripherals. Moreover,

the port relocate function is built in. It can set which I/O port the peripheral function can be allocated to.

 Capable of pull-up control per pin

 Capable of reading pin level directly

 Built-in the port relocate function

 Up to 65 high-speed general-purpose I/O Ports@80pin Package

 Some ports are 5V tolerant.

See "List of Pin Functions" and "I/O Circuit Type" to confirm the corresponding pins.

 Dual Timer (32-/16-bit Down Counter)

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

Operation mode is selectable from the followings for each channel.

 Free-running

 Periodic (=Reload)

 One-shot

 Quadrature Position/Revolution Counter (QPRC) (Max two channels)

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

encoder. Moreover, it is possible to use as the 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

 Multi-function Timer

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 × 2ch./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 time function

 Input capture function

 A/D convertor activate function

 DTIF (Motor emergency stop) interrupt function
