 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

 Real-time clock (RTC)

The Real-time clock can count Year/Month/Day/Hour/Minute/Second/A day of the week from 01 to 99.

 The interrupt function with specifying date and time (Year/Month/Day/Hour/Minute/Second/A day of the

week.) is available. This function is also available by specifying only Year, Month, Day, Hour or Minute.

 Timer interrupt function after set time or each set time.

 Capable of rewriting the time with continuing the time count.

 Leap year automatic count is available.

 Watch Counter

The Watch counter is used for wake up from sleep and timer mode.

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

 External Interrupt Controller Unit

 Up to 32 external interrupt input pins @ 176pin Package

 Include one non-maskable interrupt (NMI) input pin

 Watchdog 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 RTC, STOP, Deep standby

RTC, Deep standby STOP modes.

 CRC (Cyclic Redundancy Check) Accelerator

The CRC accelerator calculates the CRC which has a heavy software processing load, and achieves a

reduction of the integrity check processing load for reception data and storage.

CCITT CRC16 and IEEE-802.3 CRC32 are supported.

 CCITT CRC16 Generator Polynomial: 0x1021

 IEEE-802.3 CRC32 Generator Polynomial: 0x04C11DB7
