5C338A
WAFG, DAFG
Description
0
Indicating a mismatch between current time and preset alarm time
1
Indicating a match between current time and preset alarm time
2.2-7 WAFG and DAFG
Alarm_W Flag Bit and Alarm_D Flag Bit
(Default setting)
The WAFG and DAFG bits are valid only when the WALE and DALE bits have the setting of 1, which is caused
approximately 61μs after any match between current time and preset alarm time specified by the Alarm_W registers
and the Alarm_D registers. The WAFG and DAFG bits accept only the writing of 0, which disables (“H”) the INTR
pin until it is enabled (“L”) again at the next preset alarm time. Conversely, setting the WAFG and DAFG bits to 1
causes no event. The WAFG and DAFG bits will have the reading of 0 when the alarm interrupt circuit is disabled
with the WALE and DALE bits set to 0. The settings of the WAFG and DAFG bits are synchronized with the output
of the INTR pin as shown in the timing chart below.
