Data Sheet
PT7C43390
2-Wire Real-time Clock Module
*1. Once it clears, even if it enables again within a coincidene period, “L” will not be output from an INT1 pin (or INT2 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 the following part.
2.
Selected frequency steady interrupt output
When the INT1 (or INT2) 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 (or INT1 register_2), the set clock is output.
3.
Per-minute edge interrupt output
When the first minute carry is performed after the INT1 (or INT2) pin output mode is set as the per-minute edge interrupt using
status register_2, low is output from the INT1 (or INT2) pin. Since the output is held, in the INT1 pin output mode, rewrite 32kE,
INT1AE, INT1ME, and INT1FE of status register_2 to “0”, and in the INT2 pin output mode, rewrite INT2AE, INT2ME, and
INT2FE of status register_2 to “0” using serial communication to set the output to high (OFF state).
