INT
Clock/calendar monitor and setting: year (2 digits)
The data register specifies the year of the clock/calendar, e.g. 01 for 2001 or 99 for 2099.
Range: 00–99
The built-in calendar works correctly until 2099 and supports leap years. It can be set directly using Control FPWIN Pro or by executing the SET_RTC_DTBIN instruction.
