12. Overview of Functions and Description of Registers
12.1. Overview of Functions
1) Clock functions
This function is used to set and read out month, day, hour, date, minute, second, and year (last two digits)
data.
Any (two-digit) year that is a multiple of 4 is treated as a leap year and calculated automatically as such until
the year 2099.
For details, see "13.1. Description of Registers".
2) Fixed-cycle interrupt generation function
The fixed-cycle timer interrupt generation function generates an interrupt event periodically at any fixed cycle
set between 244.14
μs and 4096 minutes.
When an interrupt event is generated, the /TIRQ pin goes to low level ("L") and "1" is set to the TF bit to report
that an event has occurred..
This function can be selected from two types of operations (single-shot operations and repeated operations).
For details, see "13.2. Fixed-cycle Interrupt Function". .
3) Alarm interrupt function
The alarm interrupt generation function generates interrupt events for alarm settings such as date, day, hour,
and minute settings.
When an interrupt event occurs, the AF bit value is set to "1" and the /IRQ pin goes to low level to indicate that
an event has occurred.
For details, see "13.3. Alarm Interrupt Function".
4) Clock output function
A clock with the same frequency (32.768 kHz) as the built-in crystal resonator can be output from the FOUT pin
(CMOS output).
