PRELIMINARY INFORMATION AUG 02, 2011
The ASIC is equipped with a reset input pin which can be used to reset the chip. Any low pulse longer than
TDEBNRST on the external reset line will be sensed and causes an ASIC reset.
The ASIC contains different dynamic and static reset sources. The static sources trigger the master reset as
long as the cause for the reset persists. The dynamic sources trigger the reset for a defined minimum reset
time. After that time has expired the system reset is released. In case the dynamic source is still signaling a
reset the reset is re-triggered.
