RTC Status Register
There are three interrupts associated with the RTC, their ags are in the RTC Status register
($1C), and their respective enable bits are the RTC Control register ($1D).
RTCF
1 (set)
–
Indicates once a day interrupt has occurred. After serving this
interrupt, it is the user’s responsibility to clear this bit, otherwise the
CPU will keep on serving this once a day interrupt when a new RTC
interrupt occurs (even there is no once a day interrupt occurs).
0 (clear) –
Indicates once a day interrupt has not occurred.
ALF
1 (set)
–
Indicates alarm interrupt has occurred. After serving this interrupt, it
is the user’s responsibility to clear this bit, otherwise the CPU will
keep on serving this alarm interrupt when a new RTC interrupt
occurs (even there is no alarm interrupt occurs).
0 (clear) –
Indicates alarm interrupt has not occurred.
SECF
1 (set)
–
Indicates once a second interrupt has occurred. After serving this
interrupt, it is responsibility to clear this bit, otherwise the CPU will
keep on serving this once a second interrupt when a new RTC
interrupt occurs (even there is no once a second interrupt occurs).
0 (clear) –
Indicates once a second interrupt has not occurred.
6.2.4
RTC Control Register
RTCE
1 (set)
–
Real time clock once a day interrupt enable
0 (clear) –
Real time clock once a day interrupt disable
