21.5.3 Clock/calendar Application Examples

Application example (regular automatic start)
• Use the clock/calendar (real-time clock) function to output 1 second (Y0) signal at 8:30 am
every day. In this example, the "hour, minute data" stored in the special data register
DT90053 are used to output signal regularly.
• In DT90053, the "hour data" and "minute data" are respectively stored in the high 8 bytes
and low 8 bytes in the form of BCD. When compare this "hour, minute data" and the value of
any time (BCD), use the special internal relay R900B (= flag) to check if the time is
consistent.
