Time-base timer

Interval time: 0.256 ms to 8.3 s (external clock frequency = 4 MHz)

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 software watchdog timer.

Wild register

It can be used to replace 3 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.

• Both clock synchronous serial data transfer and clock asynchronous serial data transfer are enabled.

• The LIN function can be used as a LIN master or a LIN slave.

8/12-bit

A/D converter

6 channels

8-bit or 12-bit resolution can be selected.

8/16-bit

composite timer

2 channels

• The timer can be configured as an “8-bit timer × 2 channels” or a “16-bit timer × 1 channel”.

• It has the following functions: interval 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 channels

• Interrupt by edge detection (The rising edge, falling edge, and both edges can be selected.)

• It can be used to wake up the device from different standby modes.

On-chip debug

• 1-wire serial control

• It supports serial writing (asynchronous mode).
