*1. Once it clears, even if it enables again within a coincidene period, “L” will not be output from an INT
pin.
*2. When an alarm output is turned on by change by the program within a concidence period, “L” is
again output from an INT pin at th time of change of th following part.

(2) Selected frequency steady interrupt output
When the INT pin output mode is set as the selected frequency steady interrupt setting using status
register_2 and the frequency/duty data is set in INT1 register_1, the set clock is output.
