■ ELC

 Module operation can be initiated by event signals without using

interrupts

 Linked operation between modules is possible when the CPU is in

sleep mode

■ Reset and supply management

 Power-on reset (POR)

 Low voltage detection (LVD)

■ Clock functions

 The main clock oscillator is connectable to an 8- to 24-MHz external

crystal resonator and usable as the PLL reference clock.

 Internal 240-kHz LOCO and HOCO selectable from 16, 18, and 20

MHz

 120-kHz clock for the IWDTa

■ Real-time clock

 Adjustment functions (30 seconds, leap year, and error)

 Real-time clock counting and binary counting modes are selectable

 Time capture in response to an event-signal input

■ Independent watchdog timer

 120-kHz IWDT-dedicated on-chip oscillator clock operation

■ Useful functions for IEC60730 compliance

 Oscillation-stoppage detection, functions for self-diagnosis and

detection of disconnection for the A/D converter, clock frequency

accuracy measurement circuit, independent watchdog timer, RAM

test-assisting function by DOC, and CRCA, etc.

 Register write protection function that protects important registers

against overwriting

■ Remote control signal receiver

■ Various communications interfaces
