<1> Data length : 8 bits (LSB first)
<2> Start bits : 1 bit
<3> Stop bits : 1/2 bit
<4> Parity bits : None/even parity/odd parity
<5> Transfer rate : 8 to 4096 cycle
<6> Baudrate source clock : System clock/OSC0/OSC1/P36 input signal
<7> Wakeup function

Note: The “cycle” refers to one period of the baudrate clock source.
 AD converter
<1> 12/8 bits resolution selectable
<2> Analog input: 16 channels
<3> Comparator mode
 PWM
● _{PWM0: Multifrequency 12-bit PWM  2 channels (PWM0A and PWM0B)}
<1> 2-channel pairs controlled independently of one another
<2> Clock source selectable from system clock or OSC1
<3> 8-bit prescaler: TPWMR0= (prescaler value + 1)  clock period
<4> 8-bit fundamental wave PWM generator circuit + 4-bit additional pulse generator circuit
<5> Fundamental wave PWM mode
Fundamental wave period : 16 TPWMR0 to 256 TPWMR0
High pulse width
: 0 to (Fundamental wave period - TPWMR0)
<6> Fundamental wave + additional pulse mode
Fundamental wave period : 16 TPWMR0 to 256 TPWMR0
Overall period
: Fundamental wave period  16
High pulse width
: 0 to (Fundamental wave period - TPWMR0)
 CRC operating circuit
 Watchdog timer
<1> Driven by the base timer + internal watchdog timer dedicated counter
<2> Interrupt or reset mode selectable
 Infrared Remote Controller Receiver Circuit
1) Noise rejection function (noise filter time constant: Approx. 120s when the 32.768kHz crystal oscillator is
selected as the reference clock source)
2) Supports data encording systems such as PPM (Pulse Position Modulation) and Manchester encording
3) X’tal HOLD mode release function
 Internal Reset Function
●_{Power-on reset (POR) function}
1) POR reset is generated only at power-on time.
2) The POR release level can be selected through option configuration.
●_{Low-voltage detection reset (LVD) function}
1) LVD and POR functions are combined to generate resets when power is turned on and when power voltage
falls below a certain level.
2) The use/disuse of the LVD function and the low voltage threshold level can be selected by option
configuration.
 Interrupts (peripheral function))
● _{61 sources (33 modules), 14 vector addresses}
<1> Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any
interrupt requests of the level equal to or lower than the current interrupt are not accepted.
<2> When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the
highest level takes precedence over the other interrupts. For interrupts of the same level, the
interrupt into the smallest vector address takes precedence.
