Wild register It can be used to replace three bytes of data.
LIN-UART
A wide range of communication speed can be selected by a dedicated reload timer. It has a full duplex double buffer. Clock-synchronized serial data transfer and clock-asynchronized serial data transfer is enabled. The LIN function can be used as a LIN master or a LIN slave.

8-bit or 10-bit resolution can be selected.
1 ch.
8/16-bit composite timer
The timer can be configured as an "8-bit timer x 2 channels" or a "16-bit timer x 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.
External interrupt
6 ch.
Interrupt by edge detection (The rising edge, falling edge, or both edges can be selected.) It can be used to wake up the device from standby modes.
On-chip debug
1-wire serial control It supports serial writing. (asynchronous mode)
