Hardware/
software
watchdog timer
Reset generation cycle
- Main oscillation clock at 10 MHz: 105 ms (Min)
The sub-CR clock can be used as the source clock of the hardware watchdog timer.
Wild register
It can be used to replace three bytes of data.
I2C
1 channel
Master/Slave sending and receiving
Bus error function and arbitration function
Detecting transmitting direction function
Start condition repeated generation and detection functions
Built-in wake-up function
UART/SIO
3 channels
Data transfer with UART/SIO is enabled.
It has a full duplex double buffer, variable data length (5/6/7/8 bits), a built-in baud rate
generator and an error detection function.
It uses the NRZ type transfer format.
LSB-first data transfer and MSB-first data transfer are available to use.
Clock-asynchronous (UART) serial data transfer and clock-synchronous (SIO) serial data
transfer is enabled.
8/10-bit A/D
converter
8 channels
8-bit or 10-bit resolution can be selected.
8/16-bit
composite timer
2 channels
Each timer can be configured as an "8-bit timer
× 2 channels" or a "16-bit timer × 1 channel".
It has built-in timer function, PWC function, PWM function and input capture function.
Count clock: it can be selected from internal clocks (seven types) and external clocks.
It can output square wave.
