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.
32kHz Clock Output
The R2025S/D incorporates a 32-kHz clock output circuit configured to generate clock pulses with the oscillation
frequency of a 32.768kHz crystal oscillator for output from the 32KOUT pin (CMOS push-pull output). The 32-kHz
clock output is enabled and disabled when the CLKC pin is held high, and low or open, respectively. 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.
