Can be configured as a 2 ch × 8-bit timer or 1 ch × 16-bit timer
Built-in timer function, PWC function, PWM function and capture function
Count clock : available from internal clocks (7 types) or external clocks
With square wave output
6 ch
Interrupt by edge detection (Select rising edge/falling edge/both edges)
Can be used to recover from standby modes
Selectable from 4 kinds of low voltage detection levels
