Warning and Alarm Logic Based on
AUX1/2MON, VCC2/3, Temp, RX-P,
and IBIASMON
The DS1862A is capable of generating an alarm and/or
warning whenever an analog monitored channel goes
out of a user-defined tolerance. Temperature, bias cur-
rent (based on IBIASMON), receive power (based on
RSSI), AUX1MON, AUX2MON, and VCC2/3, are moni-
tored channels that generate latched flags. See the fig-
ure below for more detail pertaining to AUX1MON and
AUX2MON. Flags are latched into a high state the first
time a monitored channel goes out of the defined oper-
ating window and for each monitored signal there is a
Mask bit that can be set to prevent the corresponding
alarm or warning flag from being set. Once a flag is set,
it is cleared by simply reading its memory location.
