Build-in LCD driver split resistor

• Three-channel timer unit

8-bit PWM timer: (usable as both reload timer and PWM timer)

8-bit pulse width counter timer: (usable as both reload timer)

20-bit timebased counter

• Two serial interfaces

8-bit synchronous serial interface

UART (5, 7, and 8-bit transfers possible)

• External-interrupt input: 2 channels

2 channels can be used to clear the low-power consumption modes

An edge detection function is provided for each channel
