3.2 Peripherals
The following peripherals are available on the aTCA-9710 blade
3.2.1 Reset
The aTCA-9710 is automatically reset by a precision voltage monitoring circuit that detects a
drop in voltage below the acceptable operating limit of 4.85V for the 5V line and below 3.2V for
the 3.3V line. Other reset sources include the Watchdog Timer, the face plate push-button
switch and also the RESET signal from the IPMC. The aTCA-9710 responds to any of these
sources by initializing local peripherals.
A reset will be generated by the following conditions:
ƒ Power failure, +5 V supply falls below 4.1 V (typ.) or +3.3 V supply falls below
2.93 V (typ.)
ƒ Pushbutton "RESET" pressed
ƒ Watchdog time-out
ƒ IPM controller reset
