Some ports are 5V tolerant I/O
Multi-function Timer
The Multi-function timer is composed of the following blocks.
16-bit free-run timer × 3ch.
Input capture × 4ch.
Output compare × 6ch.
A/D activating compare × 3ch.
Waveform generator × 3ch.
16-bit PPG timer × 3ch.
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
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.
External Interrupt Controller Unit
Up to 8 external interrupt input pins
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 mode except RTC and STOP and Deep
standby RTC and Deep standby STOP modes.
Clock and Reset
[Clocks]
Selectable from five clock sources (2 external oscillators, 2 built-in CR oscillators, and Main PLL) .
Main Clock
Sub Clock
Built-in high-speed CR Clock
Built-in low-speed CR Clock
Main PLL Clock
: 4 MHz to 20MHz
: 32.768kHz
: 4MHz
: 100kHz
[Resets]
Reset requests from INITX pin
Power on reset
Software reset
Watchdog timers reset
Low-voltage detection reset
Clock supervisor reset
Clock Super Visor (CSV)
Clocks generated by built-in CR oscillators are used to supervise abnormality of the external clocks.
If external clock failure (clock stop) is detected, reset is asserted.
If external frequency anomaly is detected, interrupt or reset is asserted.
Low Voltage Detector (LVD)
This Series includes 2-stage monitoring of voltage on the VCC. When the voltage falls below the voltage
that has been set, Low-Voltage Detector generates an interrupt or reset.
LVD1: error reporting via interrupt
LVD2: auto-reset operation
Low-Power Consumption Mode
Six low-power consumption modes supported.

Deep standby RTC
Deep standby STOP
Back up register is 16bytes.
