M41ST95Y*, M41ST95W
18/35
To disable the alarm, write '0' to the Alarm Date
Register and to RPT1-5. The IRQ/FT/OUT output
is cleared by a READ to the Flags Register as
shown in Figure
14
. A subsequent READ of the
Flags Register is necessary to see that the value
of the Alarm Flag has been reset to '0.'
The IRQ/FT/OUT pin can also be activated in the
battery back-up mode. The IRQ/FT/OUT will go
low if an alarm occurs and both ABE (Alarm in Bat-
tery Back-up Mode Enable) and AFE are set.
The ABE and AFE Bits are reset during power-up,
therefore an alarm generated during power-up will
only set AF. The user can read the Flag Register
at system boot-up to determine if an alarm was
generated while the M41ST95Y/W was in the de-
select mode during power-up.
Figure 15., page 19
illustrates the back-up mode alarm timing.
