? Calendar count mode or binary count mode selectable

? Time capture function

? Time capture on event-signal input through external pins

■ Independent watchdog timer

? 15-kHz on-chip oscillator produces a dedicated clock signal to drive

IWDT operation.

■ Useful functions for IEC60730 compliance

? Self-diagnostic and disconnection-detection assistance functions for

the A/D converter, clock frequency accuracy measurement circuit,

independent watchdog timer, RAM test assistance functions using the

DOC, etc.
