          l Clock Sources

－ 32768Hz crystal oscillator with external crystal. － RC oscillator with external resistor.

          l Oscillator mode

－ 32768Hz crystal oscillator work only. － 32768Hz crystal oscillator and RC oscillator work together.

          l When 32768Hz crystal oscillator and RC oscillator work together, MCU supports five work modes to reduce the current consumer.

              － Normal1: MCU, 32768Hz clock and RC oscillator turn on.

              － Normal2: MCU, RC oscillator turn on, 32768Hz clock turn off.

              － Slow: MCU, 32768Hz clock turn on, RC oscillator turn off.

              － Idle: MCU, RC oscillator turn off, 32768Hz clock turn on.

              － Sleep: MCU, 32768Hz clock and RC oscillator turn off.

          l When 32768Hz crystal oscillator work only, MCU supports three work modes to reduce the current consumer.

－ Slow: MCU and 32768Hz crystal oscillator turn on.

－ Idle: MCU turn off, 32768Hz crystal oscillator turn on.

－ Sleep: MCU and 32768Hz crystal oscillator turn off.

          l 6 hard interrupt source: RTC overflow interrupt, 4 external interrupts, TCC overflow interrupt.

          l Built-in programmable sound generator (PJTMS).

          l Watchdog Timer (WDT) with its own on-chip RC oscillator to prevent system stand still.

          l Built-in power on reset (POR).

          l Oscillator Start-up Timer (OST).

          l CMOS technology for low power consumption.
