WDT
Functions as an interval timer or a watch dog timer.
(1) 16-bit timer
(2) Watch dog timer or interval timer mode can be selected
(3) Interrupt or reset generation.
(4) Maximum period: longer than 200 msec
PWM
This LSI contains two channels of PWM (Pulse Width Modulation) function which can change the duty cycle of
a waveform with a constant period. The PWM output resolution is 16 bits for each channel.
Serial Interface
This LSI contains four serial interface.
OKI Semiconductor
(1) UART without FIFO
(2) UART with 16bytes FIFO
(3) Synchronous serial interface
(4) I2C

It is a clock synchronous 8bit serial port
This is the serial port which performs data transmission, taking a synchronization per character.
Selection of various parameters, such as addition of data length, a stop bit, and a parity bit, is possible.
Based on the I2C BUS specifications. Operates as a single master device.
