(6) Periodic Interrupt Function
The RV5C387A incorporates the periodic interrupt circuit configured to generate periodic interrupt signals
aside from interrupt signals generated by the alarm interrupt circuit for output from the /INTRA pin. Periodic
interrupt signals have five selectable frequency settings of 2 Hz (once per 0.5 seconds), 1 Hz (once per 1
second), 1/60 Hz (once per 1 minute), 1/3600 Hz (once per 1 hour), and monthly (the first day of every month).
Further, periodic interrupt signals also have two selectable waveforms, a normal pulse form (with a frequency
of 2 Hz or 1 Hz) and special form adapted to interruption from the CPU in the level mode (with second,
minute, hour, and month interrupts). The condition of periodic interrupt signals can be monitored by using a
polling function.
(7) 32kHz Clock Output
The RV5C387A incorporates a 32-kHz clock circuit configured to generate clock pulses with the oscillation
frequency of a 32.768kHz crystal oscillator for output from the 32KOUT pin (Nch open drain output). The
32-kHz clock output can be disabled by certain register settings but cannot be disabled without manipulation
of any two registers with different addresses to prevent disabling in such events as the runaway of the CPU.
The 32KOUT pin is enabled at power-on from 0 volts.
