YB1921RB-F Overview

3-Pin Microprocessor Reset Monitor

YB1921
3-Pin Microprocessor Reset Monitor
Introduction
The YB1921 is a cost-effective system
supervisor Integrated Circuit (IC) designed to monitor
V
CC
in digital and mixed signal systems and provide a
warning signal when the system power supply is out
of working range, and a reset signal to the host
processor when necessary. No external components
are required.
The reset output is driven active within 20μsec
of V
CC
falling through the reset voltage threshold.
Reset is maintained active for a minimum of 140msec
after V
CC
rises above the reset threshold. The YB1921
has an active-low RESET output. The output of the
YB1921 is guaranteed valid down to V
CC
=1V.
The YB1921 is optimized to reject fast transient
glitches on the V
CC
line. Low supply current of 18μA
(V
CC
=3.3V) makes these devices suitable for battery
powered applications.

I can't figure out how to use ADS1.2 to debug interrupt programs.
When debugging with ADS, download the program to 0x3000 0000. If there is an interrupt vector at 0x00, the program debugging will succeed and enter the interrupt handler. Now the question is, how does...
