Register A, Index 0Ah;
bit 7 description
This bit is provided for use by
software that needs to modify the
time, calendar or alarm registers in
the real time clock. When this bit
reads back ‘1b’, these internal
registers are unavailable for access
by software since internal RTC logic
is using them. When this bit reads
back ‘0b’, software will have a
guaranteed minimum window of
244
μ
s in which modifications to
these registers are allowed...
The time, calendar, and alarm
information in RAM is fully available
to the program when the UIP bit is 0,
it is not in transition...
This bit is provided for use by
software that needs to either read or
write the time, calendar, or alarm
registers in the real time clock. When
this bit reads back ‘1b’, these internal
registers are unavailable for access
by software because internal RTC
logic is using them. When this bit
reads back ‘0b’, software will have a
guaranteed minimum window of
244
μ
s in which reads or writes to
these registers are guaranteed to be
valid...
The time, calendar, and alarm
information in RAM is fully available
to the program when the UIP bit is 0
because an update cycle is not in
progress...
Rewrite to clarify
meaning.
The terms
“modify” and
“modifications”
are misleading.
Both reads and
writes are
affected.
